The num_fences, count, i, and j variables in dma_fence_dedup_array() and
__dma_fence_unwrap_merge() have inconsistent integer types, mixing both
unsigned int and int.
Use type size_t consistently for these instead, and update the return
type of dma_fence_dedup_array() accordingly.

hws_bwc_matcher_move() allocates a replacement matcher before setting it
as the resize target. If mlx5hws_matcher_resize_set_target() fails, the
replacement matcher is not attached anywhere and is leaked.
Fix the leak by destroying the replacement matcher before returning from
the resize-target failure path.
The bug was first flagged by an experimental analysis tool we are
developing for kernel memory-management bugs while analyzing
v6.13-rc1. The tool is still under development and is not yet publicly
available. Manual inspection confirms that the bug is still
present in v7.1.1.
An x86_64 allyesconfig build showed no new warnings. As we do not have a
mlx5 HWS-capable device to test with, no runtime testing was able to be
performed.

IPQ5210 SoCs expose CPU frequency limits through an eFuse speed bin, and
the valid CPU OPPs depend on the SoC variant.
Add IPQ5210 support to the Qualcomm NVMEM cpufreq driver so the supported
OPPs can be selected at runtime using the eFuse value and the opp-
supported-hw OPP property. Also block the generic cpufreq-dt platform
device for IPQ5210 so the NVMEM-based driver is used.

bc8e80d56c1ec ("x86/mce: Merge mce_amd_inj into mce-inject")
removed the last .c file from arch/x86/ras/, so that there is now only
a lonely Kconfig file in this folder. Its config switches CONFIG_RAS_CEC and
CONFIG_RAS_CEC_DEBUG are only used in code that resides in drivers/ras/, so
those Kconfig switches should better reside in drivers/ras/, too. Thus move

When a debug BO command completes, job->drv_cmd may already have been
freed. Accessing it from aie2_sched_drvcmd_resp_handler() can result in
a use-after-free and memory corruption.
Fix this by introducing reference counting for drv_cmd objects and
transferring ownership to the job while it is in flight. This ensures
that the command remains valid until the completion handler finishes
processing it.

devm_gpiod_get_optional() returns NULL when the optional GPIO is absent,
but returns an ERR_PTR when the GPIO provider lookup fails, including
probe deferral.
Probe currently logs the ERR_PTR case as if the reset GPIO were simply
absent and keeps the error pointer in reset_gpio. Later ads124s_reset()
treats any non-NULL reset_gpio as a valid descriptor and passes it to
gpiod_set_value_cansleep().
Return the lookup error instead of retaining the ERR_PTR.

Like all LED drivers, pwm-multicolor supports turning on an LED on boot
by setting linux,default-trigger, e.g. to "default-on". pwm-multicolor
however scales the brightness of the color-component sub-LEDs with their
individual intensity value. Since these intensities are
zero-initialized, on boot a trigger is invisible until colors are set
from userspace.
Fix linux,default-trigger for pwm-multicolor by allowing for nonzero
default-intensities but default to 0 for backwards-compatibility.

We currently have a mixture of styles for our RTP tables with respect of
how we define the number of entries:
* xe_rtp_process_to_sr() expects to receive the number of entries as
arguments;
* xe_rtp_process() expects the array to have a sentinel at the end of
the array;
* in xe_rtp_test.c, even though xe_rtp_process_to_sr() does not
require a sentinel value, we need to rely on that technique to be
able to count xe_rtp_entry_sr entries because simply using
ARRAY_SIZE() is not possible.
The style used by xe_rtp_process_to_sr() makes it hard to share the
tables with other compilation units (e.g. kunit tests), since the number
of entries is calculated with ARRAY_SIZE(), which is done at compile
time.
Since we use the size of the tables to create some bitmasks, using a
sentinel style doesn't seem great either.
A way to reconcile things into a single style is to have a struct type
that would hold the entries array and the number of entries. Since we
have xe_rtp_entry and xe_rtp_entry_sr, we would have one type for each.
The advantage of the proposed approach is that now we have a nice way to
share the tables directly to kunit tests with information about their
size.

mt_io_flags is a single unsigned long, but mt_process_slot(),
mt_release_pending_palms() and mt_release_contacts() use it as a
per-slot bitmap indexed by the slot number. That slot number is only
bounded by td->maxcontacts, which is taken from the device's
ContactCountMaximum feature report and can be up to 255, not by
BITS_PER_LONG.
As a result, a multitouch device that advertises a large contact count
makes set_bit()/clear_bit() operate past the mt_io_flags word and
corrupt the adjacent members of struct mt_device. The sticky-fingers
release timer is the easiest way to reach this. mt_release_contacts()
runs
for (i = 0; i < mt->num_slots; i++)
clear_bit(i, &td->mt_io_flags);
with num_slots == maxcontacts. For maxcontacts around 250 the loop
clears the bits that overlap td->applications.next, zeroing that list
head, and the list_for_each_entry() that immediately follows then
dereferences NULL. The kernel panics from timer (softirq) context. On a
KASAN build this shows up as a general protection fault in
mt_release_contacts() with a null-ptr-deref at offset 0x58, which is
offsetof(struct mt_application, num_received).
The state is reachable from an untrusted USB or Bluetooth HID
multitouch device; no local privileges are required.
Store the per-slot active state in a separately allocated bitmap sized
for maxcontacts, the same pattern already used for pending_palm_slots,
and keep only MT_IO_FLAGS_RUNNING in mt_io_flags. The two
"mt_io_flags & MT_IO_SLOTS_MASK" arming checks become
bitmap_empty(td->active_slots, td->maxcontacts).
Move MT_IO_FLAGS_RUNNING back to bit 0. It was bumped to bit 32 by the
same commit to leave the low byte for the slot bits; with the slot bits
gone it fits in bit 0 again, which also keeps it within the unsigned
long on 32-bit.

Add basic version of mcf54415 DAC driver. DAC is embedded in the SoC and
DAC configuration registers are mapped in the internal IO address space.
The DAC accepts a 12-bit digital signal and creates a monotonic 12-bit
analog output varying from DAC_VREFL to DAC_VREFH. The DAC module
consists of a conversion unit, an output amplifier, and the associated
digital control blocks. Default register values for DAC_VREFL and DAC_VREFH
are respectively 0 and 0xfff, left untouched in this initial version.
This initial version of the driver is minimalistic, "output raw" only, to
be extended in the future. DMA and external sync are disabled, default mode
is high speed, default format is right-justified 12-bit on 16-bit word.

The driver was introduced in 2021 and since then only supports a single
chip variant. Simplify the driver by hard-coding the device properties
instead of using the id_table's abstraction for a single chip type.
Also drop the write-only struct member dcfg and the then unused struct
definition.

lcdif_attach_bridge() uses dev_err_probe() on all its error returns to
store a specific deferral message.
However its caller lcdif_load() calls dev_err_probe() again on error,
overwriting the specific deferral messages with a unique, unavoidably
generic, message.
Make the specific deferral message visible by using a plain 'return ret' on
the caller.

jpeg_v4_0_3_is_idle() initializes ret to false and then accumulates ring
idle status using &=. Since false & condition always remains false, the
function can never report the JPEG block as idle.
Initialize ret to true so the function returns true only when all JPEG
rings report RB_JOB_DONE.

prev_sink reference
prev_sink is unconditionally retained via dc_sink_retain at function
entry, but the DP alt mode timeout path inside SIGNAL_TYPE_DISPLAY_PORT
returns false without releasing prev_sink. All other return paths in the
function correctly call dc_sink_release(prev_sink), making this the only
missing cleanup.

SMU13 reports SocketPowerLimitAc/Dc as the default power limit, but
MsgLimits.Power may carry a different firmware bound for the same PPT
throttler. Using only the socket limit for both min and max can therefore
expose an incorrect power range.
Keep the socket limit as the default, but derive the range from both values:
use the lower value for the min base and the higher value for the max base
before applying OD percentages. Keep the current limit query independent
from the cap calculation.

Running RCCL unit tests on a system with a 64K PAGE_SIZE triggers

upstream kernel:
WARNING: drivers/gpu/drm/amd/amdgpu/amdgpu_object.c:1335 at

The warning is triggered because
amdgpu_ttm_next_clear_entity() returns NULL when a clear buffer
operation is requested. This happens because the GART window
allocation for the default_entity, clear_entity and move_entity
fails during initialization.
Commit [1] introduced separate GART windows for the
default_entity, clear_entity and move_entity of each SDMA
instance. Their sizes are derived from
AMDGPU_GTT_MAX_TRANSFER_SIZE, which is currently defined as 1024
pages. This implicitly assumes a 4K PAGE_SIZE, where 1024 pages
correspond to a 4MB transfer. On a 64K PAGE_SIZE system, however,
the same value expands to 64MB.
The default_entity and clear_entity each allocate one
AMDGPU_GTT_MAX_TRANSFER_SIZE GART window, while the move_entity
allocates two such windows. This results in 16MB of GART space
per SDMA instance on a 4K PAGE_SIZE system, but 256MB per SDMA
instance on a 64K PAGE_SIZE system.
On an MI210 system with five SDMA instances and a 512MB GART
aperture, the total GART space required becomes 1.25GB,
exceeding the available GART aperture. Consequently, GART window
allocation fails, amdgpu_ttm_next_clear_entity() returns NULL,
and the above warning is triggered.
Redefine AMDGPU_GTT_MAX_TRANSFER_SIZE in bytes instead of page
units. Where a page count is required, convert it using
PAGE_SHIFT. This preserves the existing 4MB transfer size across
all PAGE_SIZE configurations while keeping GART window
allocations within the available GART aperture.
