Pull driver core updates from Danilo Krummrich:
"container_of:
- Apply typeof_member(), remove the local __mptr variable to
eliminate variable shadowing warnings on nested container_of()
calls, and remove unnecessary parentheses
core:
- Add driver name to probe debug print for initcall_debug
- Avoid repeatedly printing the same 'Fixed dependency cycle' log
- Unwind device_add() on attribute creation failure in
attribute_container_add_class_device()
- Remove statistics group if encryption group creation fails in
transport_add_class_device()
debugfs:
- Fix lockdown check for mmap_prepare()
- Warn if file creation failed due to uninitialized debugfs
device property:
- Implement fw_devlink support for software nodes by adding
software_node_add_links(), which creates fwnode links from
DEV_PROP_REF properties to enable automatic probe ordering. Add
kunit-managed fwnode helpers and test coverage
- Fix infinite loop in fwnode_for_each_child_node() when the
secondary fwnode has more than one child. Add test cases
- Fix out-of-bounds access in software_node_get_reference_args() when
called with index -1 (UINT_MAX)
- Refactor to use RAII approach with __free()
- Add Bartosz Golaszewski as software node reviewer
firmware loader:
- Fix race where a sysfs fallback request can complete before being
queued as pending, leading to a use-after-free on the next fallback
request
- Reject 0-size built-in firmware and fail the build on empty
firmware files in CONFIG_EXTRA_FIRMWARE
kobject:
- Provide __KOBJ_ATTR() and __KOBJ_ATTR_RO/WO() initialization macros
and allow the constification of kobject attributes, enabling them
to reside in read-only memory
platform:
- Provide platform_device_set_of_node(), platform_device_set_fwnode(),
and platform_device_set_of_node_from_dev() helpers that encapsulate
firmware node reference counting for dynamically allocated platform
devices
Convert all in-tree users that manually assigned dev.of_node or
dev.fwnode, fixing a pre-existing refcount bug in powermac. Switch
to counting references of all firmware node types, not only OF
nodes
- Unify the release path for dynamically allocated platform devices
by removing platform_device_release_full(). Amend the fwnode setter
API contract to warn if a primary software node is overwritten. Add
KUnit tests for correct software node removal on device
unregistration
Rust:
- Auxiliary:
- Add registration_data_with() closure-based API for invariant
ForLt types
- Debugfs:
- Migrate BinaryWriter and BinaryReaderMut trait requirements
from kernel::transmute traits to zerocopy traits
- Device:
- Add BoundInternal device context and InternalBoundContext trait
for bus abstractions that need internal access to a bound
device.
- Make the lifetime on Core and CoreInternal invariant to prevent
coercion to shorter lifetimes
- Devres:
- Fix race between concurrent revokers where the losing revoker
could return before the winning revoker finished dropping the
inner data, causing use-after-free.
- Ensure revocation is complete before the device finishes
unbinding by making the synchronization bidirectional.
- Add DevresLt<F: ForLt>, a wrapper around Devres that shortens
'static back to the caller's borrow scope. Implement ForLt and
CovariantForLt for Bar, IoMem, and ExclusiveIoMem
- Driver:
- Switch from index-based to pointer-based device ID info lookup,
storing static references in driver_data. Centralize device ID
handling in device_id.rs, removing the open-coded ACPI/OF
matching logic and duplicate ID table from driver.rs
- I/O:
- Make I/O regions typed (with a dynamically-sized Region type
for the existing untyped case), create view types representing
subregions of a mapped I/O region, and add io_project!() for
safely creating subviews.
- Split Io into a base trait (IoBase) and an extension trait (Io)
with a blanket implementation, preventing implementers from
overriding provided methods that unsafe code relies on.
- Add a SysMem backend for shared system memory with volatile
access, and make Coherent implement Io via an I/O view type.
Add IoSysMap as sum type of Mmio and SysMem. Add copying
methods (memcpy_{from,to}io()) and read_val()/write_val() for
typed access.
- Replace dma_read!()/dma_write!() with io_read!()/io_write!()
for primitives and copying methods for aggregates; drop the old
macros. Convert nova-core to use I/O projection.
- Fix internal shortcut rule dispatch in the register!() macro,
remove unused rule arguments, and use path fragments for alias
destinations
- IRQ:
- Make irq::Registration compatible with lifetime-bound drivers
by removing the 'static bound on Handler/ThreadedHandler and
replacing Devres<RegistrationInner> with direct
request_irq()/free_irq() calls. Handlers can now directly own
lifetime-bound device resources
- PCI:
- Convert IrqVectorRegistration to a lifetime-annotated owning
type, giving drivers explicit control over the allocation
lifetime. IrqVector embeds a resolved IrqRequest, making the
conversion infallible. Remove the redundant
request_irq()/request_threaded_irq() wrappers from pci::Device.
- Add pci_irq_type() C helper and expose it via irq_type() on
IrqVectorRegistration and IrqVector, returning PCI_IRQ_MSIX,
PCI_IRQ_MSI, or PCI_IRQ_INTX.
- Mark pci::Device refcount methods inline
- Serdev:
- Add Rust abstractions for the serial device bus, including
serdev::Driver trait, serdev::Device wrapping struct
serdev_device, and serdev::Adapter implementing
RegistrationOps. Includes a sample driver. Markus Probst takes
over as serdev maintainer for both C and Rust code
- Misc:
- Split ForLt into a base trait (providing the Of<'a> GAT) and an
unsafe CovariantForLt subtrait guaranteeing covariance,
enabling invariant types (e.g. those containing Mutex<&'bound T>)
to participate in the ForLt abstraction.
- Fix Coherent read past EOF returning -ERANGE instead of zero.
- Fix firmware example UB by avoiding null-pointer ARef
misc:
- Avoid iattr allocation in kernfs listxattr by using
kernfs_iattrs_noalloc().
- Unregister SoC bus on early device registration failure.
- Remove unused DMA_FENCE_TRACE Kconfig symbol.
- Fix /sys/module path in comment.
- Refactor ISA bus init to remove nested blocks.
- Remove redundant nodemask clears in numa_init().
- Add kernel-doc for fwnode_operations and sys_soc.h, mark
internal property data as private for kernel-doc, and add
property.h/fwnode.h to driver-api infrastructure docs.
- Add MAINTAINERS entry for sys_soc.h"

qnap_mcu_exec() publishes an on-stack buffer to the receive path:
unsigned char rx[QNAP_MCU_RX_BUFFER_SIZE];
...
reply->data = rx;
reply->length = length;
and qnap_mcu_receive_buf() writes into it from the serdev receive path,
which runs out of flush_to_ldisc() and is not serialized against
qnap_mcu_exec() at all. bus_lock cannot cover it, because qnap_mcu_exec()
holds that mutex across wait_for_completion_timeout().
On a timeout qnap_mcu_exec() returns with reply->data still pointing at
its own frame. A reply that arrives late, or an unsolicited message from
the MCU, is then written into a stack frame that has been left, corrupting
whatever runs next on that stack. The same applies when qnap_mcu_write()
fails, since that path returns without touching the reply state either.
Move the receive buffer into struct qnap_mcu. It is 37 bytes and the
structure is devm_kzalloc()ed, so it lives as long as the driver, and a
late write lands in memory that is still valid and is reinitialized by the
next command. bus_lock keeps commands from sharing it.
This deliberately does not clear reply->data or reply->length on the
timeout path. Doing so races with qnap_mcu_receive_buf(), which reads both
after its
if (!reply->length)
return size;
check: clearing reply->data gives a NULL dereference, and clearing
reply->length alone removes the reply->received == reply->length exit
condition, so the copy loop runs until the uart chunk is consumed and
overruns the buffer. Leaving both set keeps the write bounded by
reply->length, which qnap_mcu_exec() has already checked against
sizeof(mcu->rx).

struct iqs62x_fw_rec includes the first data byte in its fixed-size header,
so the parser advances by len - 1 bytes after that header. A zero len makes
the size_t cursor update move back by one byte, so the next record overlaps
the current record instead of following a valid declared extent.
Reject zero-length records and express the remaining-size check without an

A received RAVE-SP frame contains protocol data followed by a
variant-specific one- or two-byte checksum. rave_sp_receive_frame() derives
a checksum pointer before proving that the frame contains the checksum,
then passes the checksum-inclusive length to handlers that index the
command, acknowledgment ID and event-data bytes or derive a reply payload
length.
Name those protocol field offsets, prove the checksum extent before
deriving the protocol-data length, pass only that data length to the
handlers, and require the complete event or reply prefix before consuming
it.

Convert the legacy gpio-keys platform device on the StrongARM SA-1100
Assabet evaluation board to use software nodes and device properties.
This allows describing the buttons and their GPIO bindings via software
nodes so that platform data support can eventually be removed from the
gpio-keys driver.
Define static software nodes for the gpio-keys device and the six button
child nodes at file scope using relative pin indexing on the UCB1x00 GPIO
controller node. In ucb1x00_assabet_add(), register the software node
group and use platform_device_register_full() to register the device.

Define a static software node for the UCB1x00 GPIO controller and attach
it to the core MFD device in ucb1x00_probe(). This node will also be

support) to reference the UCB1x00 GPIO controller in property entries
when converting legacy platform data to software nodes, resolving pin
bindings directly via the attached firmware node without relying on

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.
The mentioned robustness is relevant for a planned change to struct
spi_device_id that replaces .driver_data by an anonymous union.
Also adapt spacing and usage of commas to the most common style.
This patch doesn't modify the compiled array, only its representation
in source form benefits.

Move the DBx500 PRCMU definitions into the DB8500 PRCMU
header and delete the wrapper header.
Convert users of simple PRCMU wrappers to call the DB8500 helpers
directly.
The dbx500-prcmu.h header was the result of an earlier attempt to
abstract several DBx5x SoC PRCMU units to use the same abstract
header. They are deleted from the kernel and this is not just
causing maintenance burden and build errors.
The stub code is using -ENOSYS in a way checkpatch complains about
so replace these with -EINVAL while we're at it.

axp20x_power_off() triggers shutdown by writing AXP20X_OFF (BIT(7)) to
the power-off control register with regmap_write(), which rewrites the
whole register and clears other control bits in it.
On the AXP221/AXP223 (and the register-compatible AXP228) - that
register also holds the CHGLED auto-control bit.
Clearing it during an orderly shutdown disables the hardware charge
indicator, so the charge LED stays dark while the board is powered off
and charging. Other variants keep unrelated configuration in the same
register too.
Set only the power-off bit with regmap_set_bits() and leave the rest of
the register untouched. The shutdown register is readable on every
variant, so the read-modify-write should be safe.
Tested on a ClockworkPi uConsole (Raspberry Pi Compute Module 4, AXP228,
which enumerates as AXP221): register AXP20X_OFF_CTRL reads 0x08 at
runtime, so the old code left it 0x80 whereas setting only BIT(7)
leaves 0x88. Writing 0x88 at power-off enables the charge LED
while still powering off the PMIC.

ipaq_micro_str() decodes a UTF-16LE string into an ASCII string.
It copies characters to a stack buffer retstr, but fails to
null-terminate it. When kstrdup() is called on retstr, it can read past
the buffer into uninitialized stack memory, potentially leaking stack
contents.
Fix this by initializing retstr to zero.

The SI476X driver depends on the legacy GPIO API. As it only
really use a single GPIO for reset, and this can be easily converted
to use a GPIO descriptor, modernize the driver.
The "reset" GPIO is obtained from a device property, such as a
device tree ("reset-gpios", which is standard, but this hardware has
no DT bindings as of now) or a software node for static platforms.
Out-of-tree users can easily adopt to providing a GPIO descriptor
this way.

gpio: legacy interface cleanups for 7.3
These are the remaining patches for legacy gpio interface
cleanup, ensuring that files referencing them are sure to
have CONFIG_GPIOLIB_LEGACY set, and use linux/gpio/legacy.h
instead of the old linux/gpio.h header.
There are a few more patches already merged in other
branches for 7.3, including soc, led, net and media. Once
everything is in, we can apply the final patches to turn
off CONFIG_GPIOLIB_LEGACY by default and remove the obsolete
header file.
This branch is based on the immutable ib-mfd-legacy-gpio-7.3
branch from mfd.git to avoid a conflict in the rohm drivers.

cros_ec_check_features() does not return an error if the underlying
EC_CMD_GET_FEATURES command fails. Consequently, when the Fingerprint
device fails to respond, the probe function ignores the failure and falls
back to installing it as 'cros_ec' device instead of 'cros_fp'.
This leads to a sysfs duplicate filename collision later when the real
'cros_ec' device attempts to register:
cros-ec-spi spi5.0: EC failed to respond in time
cros-ec-dev.19.auto: cannot get EC features: -110
sysfs : cannot create duplicate filename '/class/chromeos/cros_ec'
: sysfs_do_create_link_sd+0x94/0xdc
: ec_device_probe+0x150/0x4f0
Fix this by explicitly calling the newly introduced cros_ec_read_features()
function. If the transfer fails, abort the broken device initialization.
Move the initialization of class_dev before this call to prevent a missing
release() callback warning on the error path.

platform_device_release() when the last reference to the device's

This works fine for devices created with platform_device_register_full()
but users of the split approach (platform_device_alloc() +
platform_device_add()) must bump the reference of the of_node they
assign manually. Add the missing call to of_node_get().

The twl4030-power driver contains two checks for ARM machine IDs via
machine_is_*() macros. The two boards concerned now support only FDT
booting, which does not use machine IDs, and therefore the code should
be updated to check the DT compatible property instead.
The legacy board files for these machines were removed in
commit 1b383f44aabc ("ARM: OMAP2+: Drop board file for 3430sdp") and
commit e92fc4f04a34 ("ARM: OMAP2+: Drop legacy board file for LDP").
The presence of these machine ID checks prevents the removal of machine
IDs no longer used by the kernel from arch/arm/tools/mach-types,
because the machine_is_*() macros are generated from mach-types. To
resolve this issue, use of_machine_is_compatible() instead.
