8cef9b451d spi: microchip-core: Fix an error handling path in mchp_corespi_probe()
mchp_corespi_init() calls mchp_corespi_enable_ints(), so
mchp_corespi_disable_ints() should be called if an error occurs after
calling mchp_corespi_init(), as already done in the remove function.

regulator: spacemit: Align input supply name with the DT binding
The Device Tree binding schema for the SpacemiT P1 PMIC defines the main
input supply property as "vin-supply", but the driver defines the supply
name for BUCK and ALDO regulators as "vcc".

This causes the regulator core to lookup for a non-existent "vcc-supply".
Rename the supply from "vcc" to "vin", to match the DT binding and ensure
that the regulators input supplies are correctly resolved.

After this change, the regulators supply hierarchy is correctly reported:

Pull io_uring updates from Jens Axboe:
 "Followup set of fixes for io_uring for this merge window. These are
  either later fixes, or cleanups that don't make sense to defer. This
  pull request contains:

   - Fix for a recent regression in io-wq worker creation

   - Tracing cleanup

   - Use READ_ONCE/WRITE_ONCE consistently for ring mapped kbufs. Mostly
     for documentation purposes, indicating that they are shared with
     userspace

   - Fix for POLL_ADD losing a completion, if the request is updated and
     now is triggerable - eg, if POLLIN is set with the updated, and the
     polled file is readable

   - In conjunction with the above fix, also unify how poll wait queue
     entries are deleted with the head update. We had 3 different spots
     doing both the list deletion and head write, with one of them
     nicely documented. Abstract that into a helper and use it
     consistently

   - Small series from Joanne fixing an issue with buffer cloning, and
     cleaning up the arg validation"

2fb6915fa2 compiler_types.h: add "auto" as a macro for "__auto_type"
"auto" was defined as a keyword back in the K&R days, but as a storage
type specifier.  No one ever used it, since it was and is the default
storage type for local variables.

C++11 recycled the keyword to allow a type to be declared based on the
type of an initializer.  This was finally adopted into standard C in
C23.

gcc and clang provide the "__auto_type" alias keyword as an extension
for pre-C23, however, there is no reason to pollute the bulk of the
source base with this temporary keyword; instead define "auto" as a
macro unless the compiler is running in C23+ mode.

This macro is added in <linux/compiler_types.h> because that header is
included in some of the tools headers, wheres <linux/compiler.h> is
not as it has a bunch of very kernel-specific things in it.

bcd752c706 drm/panel-edp: Add AUO B140QAX01.H panel
A 14-inch 2560x1600 60Hz matte touch panel, found on a Dell Latitude 7455
laptop (second-source with BOE NE14QDM), according to online sources it's
also found on the Latitude 7440 and some ASUS models.

Don't have datasheet access, but the same timing as for other panels from

9aeed90419 alpha: don't reference obsolete termio struct for TC* constants
Similar in nature to ab10727660. glibc-2.42
drops the legacy termio struct, but the ioctls.h header still defines some
TC* constants in terms of termio (via sizeof). Hardcode the values instead.

This fixes building Python for example, which falls over like:
  ./Modules/termios.c:1119:16: error: invalid application of 'sizeof' to incomplete type 'struct termio'

3cec82b4fc alpha: Replace __ASSEMBLY__ with __ASSEMBLER__ in the alpha headers
While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a
macro that only gets defined by the Makefiles in the kernel.
This can be very confusing when switching between userspace
and kernelspace coding, or when dealing with uapi headers that
rather should use __ASSEMBLER__ instead. So let's standardize now
on the __ASSEMBLER__ macro that is provided by the compilers.

This is a completely mechanical patch (done with a simple "sed -i"
statement).

16bd954c93 rtc: spacemit: MFD_SPACEMIT_P1 as dependencies
RTC_DRV_SPACEMIT_P1 is a subdevice of P1 and should depend on
MFD_SPACEMIT_P1 rather than selecting it directly. Using 'select'
does not always respect the parent's dependencies, so 'depends on'
is the safer and more correct choice.

Additionally, the default value depends on MFD_SPACEMIT_P1 rather
than ARCH_SPACEMIT.

The drm_kms_helper_poll_fini() and drm_atomic_helper_shutdown() helpers
should only be called when the device has been successfully registered.
Currently, these functions are called unconditionally in tilcdc_fini(),
which causes warnings during probe deferral scenarios.

Fix this by rewriting the failed probe cleanup path using the standard
goto error handling pattern, which ensures that cleanup functions are
only called on successfully initialized resources. Additionally, remove
the now-unnecessary is_registered flag.

 - Samsung Exynos derived Axis Communications ARTPEC-9 SoC support.
   These guys literally live next door to me, ARTPEC spells out
   "Axis Real-Time Picture Encoding Chip" and is tailored for camera
   image streams and is something they have evolved for a quarter of

49a51df427 rtc: Add new rtc-macsmc driver for Apple Silicon Macs
Apple Silicon Macs (M1, etc.) have an RTC that is part of the PMU IC,
but most of the PMU functionality is abstracted out by the SMC.
On T600x machines, the RTC counter must be accessed via the SMC to
get full functionality, and it seems likely that future machines
will move towards making SMC handle all RTC functionality.

The SMC RTC counter access is implemented on all current machines
as of the time of this writing, on firmware 12.x. However, the RTC
offset (needed to set the time) is still only accessible via direct
PMU access. To handle this, we expose the RTC offset as an NVMEM
cell from the SPMI PMU device node, and this driver consumes that
cell and uses it to compute/set the current time.

40d8123ff7 MAINTAINERS: drop unneeded file entry in NVIDIA VRS RTC DRIVER
Commit 9d6d6b0693 ("rtc: nvvrs: add NVIDIA VRS RTC device driver") adds
the section NVIDIA VRS RTC DRIVER in MAINTAINERS, which refers to the
non-existing file include/linux/rtc/rtc-nvidia-vrs10.h

Note, with the changes of v6 to v7 of the patch series adding the driver,
the content of this include file was moved into the driver file, and the
include file was dropped from that patch. It was simply missed to adjust
the section in MAINTAINERS that was newly added with that patch.

Drop the file entry to this non-existing file accordingly now.

6ada8e2423 rtc: renesas-rtca3: Add support for multiple reset lines
Switch from devm_reset_control_get_shared() to
devm_reset_control_array_get_shared() when retrieving resets.

The RZ/V2H SoC requires two resets for the RTC block instead of one,
so this will allow to handle multiple resets without additional changes.

4800046b56 dt-bindings: rtc: renesas,rz-rtca3: Add RZ/V2H support
The Renesas RZ/V2H RTC IP is based on the same RTCA3 IP as RZ/G3S
(r9a08g045), with the following differences:
- It lacks the time capture functionality
- The maximum supported periodic interrupt frequency is 128Hz instead
  of 256Hz
- It requires two reset lines instead of one

Add new compatible string "renesas,r9a09g057-rtca3" for RZ/V2H and update
the binding accordingly:
- Allow "resets" to contain one or two entries depending on the SoC.
- Add "reset-names" property, but make it required only for RZ/V2H.

73c4638a28 rtc: s35390a: use u8 instead of char for register buffer
The register buffer in s35390a_get_reg() was previously defined as
`char *buf`. This is not ideal since register data represents raw
binary values rather than textual data.

Switch the type to `u8 *buf` to better reflect its intended usage and
to avoid potential issues with sign extension when handling register
values on platforms where `char` is signed by default.

This change improves type safety and makes the code consistent with
other RTC drivers that operate on raw register data.

5630f7557d btrfs: do not skip logging new dentries when logging a new name
When we are logging a directory and the log context indicates that we
are logging a new name for some other file (that is or was inside that
directory), we skip logging the inodes for new dentries in the directory.

This is ok most of the time, but if after the rename or link operation
that triggered the logging of that directory, we have an explicit fsync
of that directory without the directory inode being evicted and reloaded,
we end up never logging the inodes for the new dentries that we found
during the new name logging, as the next directory fsync will only process
dentries that were added after the last time we logged the directory (we
are doing an incremental directory logging).

So make sure we always log new dentries for a directory even if we are
in a context of logging a new name.

We started skipping logging inodes for new dentries as of commit
c48792c6ee ("btrfs: do not log new dentries when logging that a new name
exists") and it was fine back then, because when logging a directory we
always iterated over all the directory entries (for leaves changed in the
current transaction) so a subsequent fsync would always log anything that
was previously skipped while logging a directory when logging a new name
(with btrfs_log_new_name()). But later support for incrementally logging
a directory was added in commit dc2872247e ("btrfs: keep track of the
last logged keys when logging a directory"), to avoid checking all dir
items every time we log a directory, so the check to skip dentry logging
added in the first commit should have been removed when the incremental
support for logging a directory was added.

A test case for fstests will follow soon.

266273eaf4 btrfs: don't log conflicting inode if it's a dir moved in the current transaction
We can't log a conflicting inode if it's a directory and it was moved
from one parent directory to another parent directory in the current
transaction, as this can result an attempt to have a directory with
two hard links during log replay, one for the old parent directory and
another for the new parent directory.

The following scenario triggers that issue:

1) We have directories "dir1" and "dir2" created in a past transaction.
   Directory "dir1" has inode A as its parent directory;

2) We move "dir1" to some other directory;

3) We create a file with the name "dir1" in directory inode A;

4) We fsync the new file. This results in logging the inode of the new file
   and the inode for the directory "dir1" that was previously moved in the
   current transaction. So the log tree has the INODE_REF item for the
   new location of "dir1";

5) We move the new file to some other directory. This results in updating
   the log tree to included the new INODE_REF for the new location of the
   file and removes the INODE_REF for the old location. This happens
   during the rename when we call btrfs_log_new_name();

6) We fsync the file, and that persists the log tree changes done in the
   previous step (btrfs_log_new_name() only updates the log tree in
   memory);

7) We have a power failure;

8) Next time the fs is mounted, log replay happens and when processing
   the inode for directory "dir1" we find a new INODE_REF and add that
   link, but we don't remove the old link of the inode since we have
   not logged the old parent directory of the directory inode "dir1".

As a result after log replay finishes when we trigger writeback of the
subvolume tree's extent buffers, the tree check will detect that we have
a directory a hard link count of 2 and we get a mount failure.

Fix this by never logging a conflicting inode that is a directory and was
moved in the current transaction (its last_unlink_trans equals the current
transaction) and instead fallback to a transaction commit.

A test case for fstests will follow soon.

87213b0d84 ublk: allow non-blocking ctrl cmds in IO_URING_F_NONBLOCK issue
Handling most of the ublksrv_ctrl_cmd opcodes require locking a mutex,
so ublk_ctrl_uring_cmd() bails out with EAGAIN when called with the
IO_URING_F_NONBLOCK issue flag. However, several opcodes can be handled
without blocking:
- UBLK_CMD_GET_QUEUE_AFFINITY
- UBLK_CMD_GET_DEV_INFO
- UBLK_CMD_GET_DEV_INFO2
- UBLK_U_CMD_GET_FEATURES

Handle these opcodes synchronously instead of returning EAGAIN so
io_uring doesn't need to issue the command via the worker thread pool.

7329417fc9 drm/amd/display: shrink struct members
On a 32-bit ARM system, the audio_decoder struct ends up being too large
for dp_retrain_link_dp_test.

link_dp_cts.c:157:1: error: the frame size of 1328 bytes is larger than
1280 bytes [-Werror=frame-larger-than=]

This is mitigated by shrinking the members of the struct and avoids
having to deal with dynamic allocation.

feed_back_divider is assigned but otherwise unused. Remove both.

pixel_repetition looks like it should be a bool since it's only ever
assigned to 1. But there are checks for 2 and 4. Reduce to uint8_t.

Remove ss_percentage_divider. Unused.

Shrink refresh_rate as it gets assigned to at most a 3 digit integer
value.

cf841f6abc drm/amd/display: Refactor dml_core_mode_support to reduce stack frame
[WHAT]
When compiling Linux kernel with clang, the following warning / error
messages pops up:

drivers/gpu/drm/amd/amdgpu/../dal-dev/dc/dml2_0/display_mode_core.c:6853:12:
error: stack frame size (2120) exceeds limit (2056) in
'dml_core_mode_support' [-Werror,-Wframe-larger-than]
 6853 | dml_bool_t dml_core_mode_support(struct display_mode_lib_st
*mode_lib)

[HOW]
Refactoring CalculateVMRowAndSwath_params assignments to a new function
helps reduce the stack frame size in dml_core_mode_support.

b7851f8c66 drm/amdkfd: Trap handler support for expert scheduling mode
The trap may be entered with dependency checking disabled.
Wait for dependency counters and save/restore scheduling mode.

v2:

Use ttmp1 instead of ttmp11. ttmp11 is not zero-initialized.
While the trap handler does zero this field before use, a user-mode
second-level trap handler could not rely on this being zero when
using an older kernel mode driver.

v3:

Use ttmp11 primarily but copy to ttmp1 before jumping to the
second level trap handler. ttmp1 is inspectable by a debugger.
Unexpected bits in the unused space may regress existing software.
