ASoC: Fixes for v7.3
A fairly big batch of fixes that came in during the merge window.
There's a lot of quirks for x86 systems and a bunch of driver specific
fixes, the most critical being the fixes for Tegra's register
definitions. It turned out that they had been relying on the regmap
default handling bugs that were fixed in v7.2 and so audio was fairly
badly broken, unfortunately the issue wasn't noticed in time for
release.

The kcontrol LED state layer tries to track the all associated
kcontrol elements with naive assumptions that they are readable.
But one can create a write-only element that has no get callback (even
a user element can do it), and this may lead to a NULL dereference at
the call chain of snd_ctl_led_notify(), as found by syzkaller.
For avoiding the Oops, add a sanity check of the kcontrol's info and
get callbacks, and just skip the invalid kcontrols before assigning
the kctl to the LED layer.

The snd_soc_dapm_put_enum_double() rejects item[0] once it reaches
e->items, but it lets item[1] be equal to it. Both go on to
snd_soc_enum_item_to_val(), which indexes e->values with no bound of
its own, so an enum with a value table reads one element past the end.
The indexing arrived with the MUX consolidation, which relaxed the
item[1] check in the same hunk. The value MUX handler it deleted used
>= there, and the snd_soc_put_enum_double() in soc-ops.c still does.
Only adav80x pairs a value table with two shifts, and its second
channel looks accidental, but the control does report two values.
Writing three into it reads off the end of adav80x_mux_values. The
core catches that only under CONFIG_SND_CTL_INPUT_VALIDATION, which
defaults off.

The BIOS on the HP OmniBook X Flip 16-cc0xxx (board 8EA2) reports
acp-audio-config-flag = FLAG_AMD_LEGACY_ONLY_DMIC. This binds the
legacy ACP driver and registers a PDM-only card, so the SoundWire
links are never scanned and the two TAS2783 speaker amplifiers and
RT712-VB codec do not enumerate.
Add a DMI entry for board 8EA2 to the ACP70 ACPI flag override table
so the firmware-provided flag is overridden and snd_pci_ps probes
instead.
On the affected system, an otherwise identical upstream kernel
without this entry binds snd_acp_pci, enumerates no SoundWire slave
devices and exposes no internal speaker PCM. With the entry added,
snd_pci_ps binds, both TAS2783 amplifiers and the RT712-VB enumerate
over SoundWire, and the amd-soundwire card exposes the internal
speaker playback PCM.
Developed with AI assistance. ChatGPT helped analyze the ACP and
SoundWire behavior, structure the controlled A/B testing, and draft
the patch changelog. All hardware measurements, kernel builds,
reboots and playback tests were performed by the submitter. The

The DMA channel request code currently warns about legacy DMA failures
when the channel name is not present in dma-names. This can report a
firmware lookup failure as a legacy DMA failure.
Furthermore, failures from the legacy DMA path are already reported by
find_candidate(), making these warnings redundant.
Only warn when the channel name is present in dma-names but the request
fails, avoiding misleading and duplicate error messages.

While we attempted to work around the false-positive lockdep warning
due to the nested mutex lock in rawmidi at the open path for a UMP
legacy rawmidi, it didn't cover the similar locking at its close path,
and this still caused another false-positive reports by syzkaller.
Add a similar workaround to snd_rawmidi_kernel_release() as done in
the former commit 9c04742e73b3 ("ALSA: rawmidi: Work around
false-positive mutex lockdep warning") to cover completely.

HP Laptop 15-fd0039nt (SSID 103c:8bb6) needs a quirk to control the
speaker mute LED via VREF100 on NID 0x1a (active-high).
This patch replaces the previous ALC236_FIXUP_HP_MICMUTE_LED_ONLY
with ALC236_FIXUP_HP_15_FD0XXX, which covers both mic mute (GPIO0)
and speaker mute (NID 0x1a) LEDs.
Use spec->no_shutup_pins instead of a custom shutup hook, as suggested
by Takashi Iwai.

A failed system resume can leave the card unusable until reboot.
usb_audio_resume() jumps to err_out when snd_usb_pcm_resume() or
snd_usb_mixer_resume() fails. The error path skips the out: block, which
restores D0 and decrements chip->num_suspended_intf.
The card stays in SNDRV_CTL_POWER_D3hot, so later control access blocks in
snd_power_ref_and_wait(). USB core logs an interface resume callback error.
It does not retry that callback, so a later callback cannot complete the
skipped cleanup.
usb_audio_suspend() increments num_suspended_intf before returning success.
A system-resume callback must consume the system-suspend count even if a
component resume fails. Otherwise, the stranded count skews later suspend
and resume cycles.
Do not apply this cleanup to runtime-resume errors. Runtime PM can retry
-EAGAIN or -EBUSY without another suspend callback. The count must continue
to describe that suspended interface. Other runtime-resume errors latch
runtime_error in the PM core and do not cause an immediate callback retry.
Both parts of the system-resume error path are longstanding. Commit
88a8516a2128a ("ALSA: usbaudio: implement USB autosuspend") introduced
err_out past the D0 restore. Commit 862b2509d157c ("ALSA: usb-audio: Fix
inconsistent card PM state after resume") later moved
num_suspended_intf-- into the out: block. The error path now skips both
operations.
No third-party code is needed to reach the error path.
snd_usb_mixer_resume() ends in snd_usb_mixer_activate(), which returns the
result of usb_submit_urb() for devices that have a mixer status URB. Its
mixer->private_resume hook can also fail through scarlett2_init_notify().
snd_usb_pcm_resume() issues a SET_CUR request to a UAC3 power domain. It
can return -EPIPE or -EIO when the device stalls the request.
Route a component error through out: only when system_suspend is nonzero.
Continue to return runtime-resume errors through err_out. Later component
resume stages remain skipped. The original error still reaches USB core.
A later transfer can fail if the device did not recover.
I reproduced the system-resume failure on an Audient iD14 MkI with an
out-of-tree diagnostic mixer resume hook. An injected -EIO on the unpatched
core left control readers in uninterruptible sleep in
snd_power_ref_and_wait() until a reboot. With this patch, the same failure
restored control access. A second system suspend and resume also succeeded
after I disabled fault injection.

The M-Audio Venom (0763:2084) does not answer any GET_CUR request
of its feature units, hanging up the USB microcontroller and
"responding" with timeouts. So the mixer building lasts around 47
seconds, and the device does not stream at all.
The same GET_CUR requests issued through libusb (with no kernel
driver bound) complete correctly and blazingly fast. So it seems
to only happen during the initial probe.
I defined an explicit composite quirk to bypass the mixer creation,
as it is not needed (the synth already comes with volume controls).
With both this and the device flag applied, the synth works
flawlessly.

The M-Audio Venom (0763:2084) is an USB Audio Class 1 compliant
synth with an integrated audio interface, it does not implement
GET_CUR on SAMPLING_FREQ_CONTROL, hanging up if requested on
endpoint 0.
The first class request issued by the driver after enumeration is
a GET_CUR on endpoint 0x02, freezing the device's USB microcontroller.
Timing out on every transfer afterwards with -ETIMEDOUT, such as
SET_INTERFACE, so neither the mixer nor any streaming interface is set up.
Analyzing a USBPcap capture of the Windows driver I found it never
requests the sampling frequency, as the synth exposes a single
discrete of 44100Hz on both streaming interfaces, thus asking for it
is unnecessary.
So I applied get_sample_rate to avoid this check, and
disable_autosuspend because the synth doesn't come back from being
suspended.

snd_usbmidi_novation_output() lays out a two-byte header at
transfer_buffer[0..1] and passes &transfer_buffer[2] together with a
length of ep->max_transfer - 2 to snd_rawmidi_transmit():
count = snd_rawmidi_transmit(ep->ports[0].substream,
&transfer_buffer[2],
ep->max_transfer - 2);
ep->max_transfer comes from the output endpoint's wMaxPacketSize via
usb_maxpacket(). A malformed or malicious device can advertise a bulk
OUT endpoint with a wMaxPacketSize of 1 - the USB core only clamps this
value downwards - so ep->max_transfer becomes 1 and the count argument
becomes -1.
snd_rawmidi_transmit() passes the negative count on to
__snd_rawmidi_transmit_peek(), where "if (count1 > count) count1 = count"
leaves count1 negative; get_aligned_size() keeps it negative for a
byte-stream substream, so the following memcpy(buffer, ..., count1) runs
with a (size_t)-1 length and writes far past the transfer buffer, which
was allocated with usb_alloc_coherent(ep->max_transfer).
This is the same class of bug that was fixed for snd_usbmidi_akai_output()
in commit 0970274613fb ("ALSA: usb-audio: fix OOB write in
snd_usbmidi_akai_output()"); the novation output routine was left
unguarded. Bail out when the endpoint cannot hold the two-byte header
plus at least one payload byte.

Add the iD14 MkI USB ID to the existing audient_id14_map. This
names feature unit 12 Monitor Mix Playback Volume.
Live meter A/B testing on MkI USB ID 2708:0002 reproduced the same
asymmetric attenuation seen on MkII. At ALSA value 104, the right
channel was 23.07 dB below the left. At 127, both channels were equal.
The misleading Speaker Playback Volume name causes PipeWire to adopt
FU12 as the stream master. Reuse the existing map to keep the control
available while preventing that selection.
Hardware-tested on Bazzite 7.2.0-ogc4.1.fc44.x86_64 with this change
backported. ALSA exposed Monitor Mix Playback Volume after module load
and USB reconnect. PipeWire volume changes from 100% to 35% and back
left all four FU12 values at 127. Channel-isolated left/right playback
remained balanced after reconnect.
Build-tested with CONFIG_SND_USB_AUDIO=m using the focused sound/usb
target.

The Logitech PRO X Wireless is a wireless headset with a hotpluggable
microphone.
Its Playback mixer's GET_CUR somehow becomes broken when the microphone
is detached, so set QUIRK_FLAG_MIXER_GET_CUR_OK to prevent the mixer
behavior from depending on whether the microphone is attached.
Meanwhile, the Playback mixer's minimum value doesn't work properly,
thus set QUIRK_FLAG_MIXER_PLAYBACK_MIN_MUTE to prevent userspace audio
stack from using the minimum mixer value to tune volume (setting it
when muted is OK).

The default behavior of sticky check now becomes what
QUIRK_FLAG_MIXER_GET_CUR_BROKEN originally does, so the quirk flag is no
longer needed.
On some devices, whether their GET_CUR being sticky depends on whether
hotpluggable components are present. When the hotpluggable components
are missing on probe, their GET_CUR behavior is classified as broken.
Therefore, reverse QUIRK_FLAG_MIXER_GET_CUR_BROKEN as
QUIRK_FLAG_MIXER_GET_CUR_OK, so that it can be set to prevent the
heuristics from gating GET_CUR.
Note that even if the quirk flag is set, init_cur_mix_raw() should still
initialize the mixer value to cval->min, otherwise restoring the bogus
saved value on the first channel could lead to unbalanced channels.

Currently, a mixer is disabled when its GET_CUR is sticky, causing
userspace to fall back to soft mixers, unless
QUIRK_FLAG_MIXER_GET_CUR_BROKEN is set. This leads to issues on some
wireless headphones with broken GET_CUR but effective SET_CUR, which use
poorly-performed lossy codecs and are prone to audible distortion at low
volume. They have to set the quirk flag to reeanble the mixer.
Considering that users can always opt into soft mixers if they need it,
i.e., when SET_CUR is stubbed, demote the severity of sticky GET_CUR by
marking GET_CUR as broken and only provide mixer values from the cache.
The mixer itself is still registered.

The SMSL USB DAC with USB ID 152a:85dd produces an audible pop
when snd-usb-audio performs its redundant probe-time interface setup.
It also pops when returning from runtime suspend.
Skip the probe-time interface setup and disable runtime autosuspend for
this device. Both flags have been verified through the quirk_flags module
parameter.
Keep QUIRK_FLAG_DSD_RAW in the device entry because the exact match takes
precedence over the generic 0x152a vendor entry from which the device
currently inherits that flag.

On Intel Hades Canyon systems with an ALC700 codec, analog audio can
become unusable after rebooting from Windows into Linux.
The affected system uses codec subsystem ID 8086:2073. In the broken
state, Realtek coefficient 0x1b has value 0x4a4b. Setting bit 0x0400
changes it to 0x4e4b and immediately restores normal analog playback.
The BIOS also sets this bit after disabling and re-enabling onboard
audio, while Windows may leave it cleared. Linux currently does not
restore it during codec initialization.
Add a machine-specific fixup for Intel Hades Canyon which sets only
bit 0x0400 of coefficient 0x1b during HDA_FIXUP_ACT_INIT.
The fix has been verified across Windows -> Linux reboots on an Intel
NUC8i7HNB with an ALC700 codec.

allowing the mmap lock to be dropped during fault handling via a new
hmm_range_fault_locked() helper.
By accepting a locked pointer and signaling retry status when lock
release occurs, it enables page fault resolution in userfaultfd
regions while preserving backward compatibility for existing callers.
- "mm: make VMA page offset handling more consistent" (Lorenzo Stoakes)
Clean up and standardize how vma->vm_pgoff is accessed and
manipulated across file-backed and anonymous mappings in the kernel
It introduces dedicated helper functions such as vma_start_pgoff(),
vma_end_pgoff(), vma_set_pgoff() and linear_page_delta() while
renaming rmap interval tree helpers to better reflect their
functionality.
These changes establish a cleaner foundation for future work that
will unify virtual page offset indexing for all anonymous and CoW'd
folios.
- "mm: handle device-private PMDs in walk callbacks" (Usama Arif)
Address kernel panics and state corruption caused by MM walk
callbacks reaching non-present device-private PMD swap entries
created during HMM migrations
It ensures that functions which acquire pmd_trans_huge_lock()
properly recognize device-private PMDs instead of assuming a present
THP or a standard migration entry.
- "mm/rmap: Refactor try_to_unmap_one" (Dev Jain)
Refactor try_to_unmap_one by modularizing Hugetlb,
anonymous-lazyfree, and anonymous-swapbacked logic into dedicated
functions, laying the structural groundwork for batched anonymous
large folio unmapping.
- "Docs/ABI/damon: sysfs ABI document fixes and additions" (Song Hu)
Fix typos and fills in missing entries in the DAMON sysfs ABI
document
- "dax/kmem: atomic whole-device hotplug via sysfs" (Gregory Price)
Introduce an atomic sysfs state attribute and supporting DAX/MM
infrastructure to prevent userland races when offlining and removing
entire memory regions
By adding an unplugged state alongside standard online modes, it
enables whole-device atomic hotplug control while preserving backward
compatibility.
- "mm: convert more vm_flags_t users to vma_flags_t" (Lorenzo Stoakes)
Continue transitioning the kernel from the deprecated vm_flags_t type
to vma_flags_t across core memory management infrastructure.
It replaces legacy type usage in core functions such as do_mmap(),
unmapped area allocation, mm->def_vma_flags, and VMA operations like
mlock, mprotect, and mremap.
- "Two small patches to clean up mm/mm_slot.h" (xu xin)
Refactor mm_slot.h by introducing mm_slot_remove() to unify duplicate
slot deletion sequences in khugepaged and KSM. It also adds code
documentation explaining why mm_slot_lookup and mm_slot_insert must
remain as preprocessor macros rather than static inline functions.
- "mm/damon/core: hide core-private struct fields" (SJ Park)
Clean up DAMON core structures by consistently marking internal-only
fields with private: comment tags to prevent improper direct access
from outer layers.
It enforces encapsulation across core structures including
damon_region, damon_target, and damon_ctx and updates DAMON_SYSFS to
interact through approved access APIs instead of exposing raw struct
members.
- "mm/damon: unurgent fixes for infinite loop, NULL de-ref and races"
(SJ Park)
Address potential infinite loops, NULL dereferences, and race
conditions identified in DAMON
It fixes an infinite loop triggered by extreme user configurations, a
NULL pointer dereference within unit tests and minor monitoring
accuracy degradation caused by subtle runtime races.
- "mm/page_alloc: fixes for free_pages_nolock() on RT/UP" (Brendan
Jackman)
Fix an NMI safety flaw in __free_frozen_pages() where freeing pages
on non-SMP or PREEMPT_RT kernels can bypass can_spin_trylock() checks
via non-PCP or isolated migration paths.
It also resolves potential kernel crashes and privilege escalation
risks triggered when BPF tracing runs in NMI context alongside memory
hotplug or large allocation frees.
- "mm/page_alloc: couple of followups for recent cleanups" (Brendan
Jackman)
Clean up and update page allocator nomenclature, documentation, and
debug assertions.
It aligns internal FPI_ flags with the public "nolock" naming
convention, removes outdated internal implementation details from
high-level page allocator comments, and eliminates obsolete
VM_BUG_ON() assertions in allocation paths.
- "mm/mseal: further cleanups" (Lorenzo Stoakes)
Refactor and simplify the mseal implementation by clarifying API
boundaries and removing unnecessary code complexity.
It replaces generic do_mseal() usage outside the syscall with a
dedicated mseal_mmap_page_zero() helper for MMAP_PAGE_ZERO,
eliminates mm_struct parameters to enforce that sealing applies only
to current->mm, and streamlines overall logic and comments with no
functional changes intended.
- "mm/vmscan: fix swappiness=max and clean up per-node proactive
reclaim" (Ridong Chen)
Resolve reclaim behavior bugs and clean up function parameters across
memory reclaim paths
It fixes swappiness=max in both standard reclaim and MGLRU so
unswappable anonymous memory no longer falls back to evicting page
cache, ensures reclaim_store() returns accurate error codes instead
of collapsing all failures into -EAGAIN, and removes the obsolete
gfp_mask parameter from __node_reclaim().
- "mm: mincore: misc cleanups" (Kefeng Wang)
Clean up and simplifies the mincore code. Most importantly, it
removes the historical special behavior that always reports VM_PFNMAP
pages as non-resident.
- "mm/huge_memory: drop dead split helper variants" (Kiryl Shutsemau)
Two trivial cleanups in the folio split API
- "mm/damon: fix uninitialized DAMOS field and kunit exec expectation
bugs" (SJ Park)
Resolve minor operational and testing bugs in DAMON identified by
Sashiko. It initializes the damos->last_applied field to prevent
occasional efficiency degradation and fixes invalid memory accesses
in DAMON KUnit tests during test failure handling.
- "cleanup for stable_page_flags()" (Jinjiang Tu)
Clean up and refactor stable_page_flags() used by /proc/kpageflags
without altering functionality.
It uses BIT_ULL() to prevent shift-overflow warnings on 64-bit flag
bits, converts folio-specific flag checks to standard folio_test_*()
helpers, and removes redundant CONFIG_PAGE_IDLE_FLAG handling.
- "Batch unmap of uffd-wp file folios" (Dev Jain)
Extend batched folio unmapping support to file folios within
userfaultfd write-protect (uffd-wp) VMAs by adding batching
capabilities to pte_install_uffd_wp_if_needed().
This removes special-case restrictions on uffd-wp VMAs in
try_to_unmap_one(), significantly simplifying the function's control
flow and complexity.
- "mm/early_ioremap: clarify and clean up early_ioremap_reset()"
(Sang-Heon Jeon)
Clarify and clean up the architecture-specific usage of
__late_set_fixmap() and __late_clear_fixmap() after
early_ioremap_reset()
It adds explicit documentation regarding when early_ioremap_reset()
must be called and removes redundant macro definitions and reset
calls in the RISC-V and ARM64 architectures.
- "mm: fix reclaim storms in defrag_mode" (Johannes Weiner)
Address severe performance regressions, swap storms, and spurious
OOMs caused by vm.defrag_mode=1 under high memory pressure in Meta
production
It updates the page allocator slowpath so non-movable allocation
requests actively trigger direct reclaim and direct compaction at
pageblock_order scale, allowing them to claim whole pageblocks rather
than spinning unproductively.
- "zram: lockmap tweaks" (Sebastian Siewior)
Optimize and fix lockdep tracking for zram devices by consolidating
per-entry lockmaps and isolate lock classes across multiple instances
This reduces memory overhead by replacing per-entry lockdep_map
instances with a single map per struct zram, and assigns a dynamic
lock_class_key to each instance to prevent false deadlock reports
when different zram devices are backed by distinct filesystems.

Reorder the HDA_CODEC_QUIRK entries for 0x17aa:0x38a7 and 0x17aa:0x38a8
so that the AMD variant (TAS2781) is matched before the Intel variant's
PCI SSID (0x386f) which uses a different amplifier. This ensures the
correct fixup (ALC287_FIXUP_TAS2781_I2C) is applied to the AMD model,
restoring internal speaker functionality.

The Lenovo Yoga Pro 9 16IAH10 (PCI SSID 17aa:3846, codec SSID 17aa:3920)
uses a TAS2781 smart amplifier driven via the ALC287 codec. On this
machine the bass speaker pin (NID 0x17) is by default routed to DAC 0x03,
which has no volume amplifier capability, resulting in the right-side
woofer being barely audible while only the tweeter plays. The Windows
driver configures NID 0x17 to DAC 0x02, which is shared with the main
speaker and carries proper amp control.
Currently this machine has no PCI SSID quirk, so it falls through to the
codec SSID fallback and matches the existing 0x17aa:0x3920 entry intended
for the Yoga S990-16, applying only the TAS2781 I2C init without the DAC
routing fix.
Add a dedicated quirk for PCI SSID 17aa:3846 that forces NID 0x17 to DAC
0x02 via alc285_fixup_speaker2_to_dac1() and chains to
ALC287_FIXUP_TXNW2781_I2C so the TAS2781 amplifier initialization is
preserved.

snd_mtpav_output_timer() rearms chip->timer while holding
chip->spinlock and accesses the card-private mtpav state.
snd_mtpav_free() currently takes the same lock and calls
timer_delete() when the timer is active. This only removes a
pending timer; it does not wait for a callback that is already
running and does not prevent the callback from rearming the timer.
A callback running on another CPU can therefore continue after
snd_mtpav_free() releases the lock and access the card-private
state while the card is being torn down. It can also rearm the
timer after timer_delete() has returned.
Call timer_shutdown_sync() without holding chip->spinlock. This
waits for any running callback to finish and prevents further
rearming before the card-private mtpav state is released.

snd_ice1712_probe() performs multiple initialization steps after
snd_card_new(), but directly returns on failures from later steps
without releasing the ALSA card, causing resource leaks when
probing fails.
Use snd_devm_card_new() together with scope-based cleanup
via __free(snd_card_unref), and clear the card pointer after
successful registration to keep it alive.
