The added print statement from a recent fix causes the driver to fail
building when CONFIG_PM is disabled:
drivers/ufs/host/ufs-mediatek.c: In function 'ufs_mtk_resume':
drivers/ufs/host/ufs-mediatek.c:1890:40: error: 'struct dev_pm_info' has no member named 'request'
1890 | hba->dev->power.request,
It seems unlikely that the driver can work at all without CONFIG_PM, so
just add a dependency and remove the existing ifdef checks, rather than
adding another ifdef.

On Qualcomm automotive SoC SA8255P, platform resource like clocks,
interconnect, resets, regulators and PHY are configured remotely by
firmware.
Logical power domain is used to abstract these resources in firmware
and SCMI power protocol is used to request resource operations by
using runtime PM framework APIs such as pm_runtime_get/put_sync to
invoke power_on/_off calls from kernel respectively.

Some UFS platforms only support a limited subset of power levels.
Currently, the sysfs interface allows users to set any PM level without
validating the minimum supported value. If an unsupported level is
selected, suspend may fail.
Introduce an pm_lvl_min field in the ufs_hba structure and use it to
clamp the PM level requested via sysfs so that only supported levels are
accepted. Platforms that require a minimum PM level can set this field
during probe.

In clang version 21.1 and later the -Wimplicit-enum-enum-cast warning
option has been introduced. This warning is enabled by default and can
be used to catch .queuecommand() implementations that return another
value than 0 or one of the SCSI_MLQUEUE_* constants. Hence this patch
that changes the return type of the .queuecommand() implementations from
'int' into 'enum scsi_qc_status'. No functionality has been changed.

Uwe Kleine-König <u.kleine-koenig@baylibre.com> says:
Hello,
this is v2 of the series to make the scsi subsystem stop using the
callbacks .probe(), .remove() and .shutdown() of struct device_driver.
Instead use their designated alternatives in struct bus_type.
The eventual goal is to drop the callbacks from struct device_driver.
The 2nd patch introduces some legacy handling for drivers still using
the device_driver callbacks. This results in a runtime warning (in
driver_register()). The following patches convert all in-tree drivers
(and thus fix the warnings one after another).
Conceptually this legacy handling could be dropped at the end of the
series, but I think this is a bad idea because this silently breaks
out-of-tree drivers (which also covers drivers that are currently
prepared for mainline submission) and in-tree drivers I might have
missed (though I'm convinced I catched them all). That convinces me that
keeping the legacy handling for at least one development cycle is the
right choice. I'll care for that at the latest when I remove the
callbacks from struct device_driver.

Introduce a bus-specific probe, remove and shutdown function. For now
this only allows to get rid of a cast of the generic device to a SCSI
device in the drivers and changes the remove prototype to return
void---a non-zero return value is ignored anyhow.
The objective is to get rid of users of struct device_driver callbacks
.probe(), .remove() and .shutdown() to eventually remove these. Until
all SCSI drivers are converted, this results in a runtime warning about
the drivers needing an update because there is a bus probe function and
a driver probe function. The in-tree drivers are fixed by the following
commits.

Multiple functions in the SCSI core accept an 'int reason' argument.
The 'int' type of these arguments doesn't make it clear what values are
acceptable for these arguments. Document which values are supported for
these arguments by introducing the enumeration type scsi_qc_status. 'qc'
in the type name stands for 'queuecommand' since the values passed as
the 'reason' argument are the .queuecommand() return values.

Pull sound fixes from Takashi Iwai:
"The only slightly large change is the enablement of CIX HD-audio
controller, which took a bit time to be cooked up, while most of other
changes are device-specific small trivial fixes:
- Default disablement of the kconfig for decades old pre-release
alsa-lib PCM API; it's only the default config value change, so it
can't lead to any regressions for the existing setups
- Support for CIX HD-audio controller
- A few ASoC ACP fixes
- Fixes for ASoC cirrus, bcm, wcd, qcom, ak platforms
- Trivial hardening for FireWire and USB-audio

* tag 'dma-mapping-6.19-2025-12-10' of git://git.kernel.org/pub/scm/linux/kernel/git/mszyprowski/linux:
dma-mapping: Fix DMA_BIT_MASK() macro being broken
dma/pool: eliminate alloc_pages warning in atomic_pool_expand
This patch adds trace points to the Ceph filesystem MDS client:
- request submission (CEPH_MSG_CLIENT_REQUEST) and completion
(CEPH_MSG_CLIENT_REPLY)
- capabilities (CEPH_MSG_CLIENT_CAPS)
These are the central pieces that are useful for analyzing MDS
latency/performance problems from the client's perspective.
In the long run, all doutc() calls should be replaced with
tracepoints. This way, the Ceph filesystem can be traced at any time
(without spamming the kernel log). Additionally, trace points can be
used in BPF programs (which can even deference the pointer parameters
and extract more values).

Commit 2b6a3f061f ("mm: declare VMA flags by bit") significantly
refactors the header file include/linux/mm.h. In that step, it introduces
a typo in an ifdef, referring to a non-existing config option
STACK_GROWS_UP, whereas the actual config option is called STACK_GROWSUP.
Fix this typo in the mm header file.

min_order_for_split() returns -EBUSY when the folio is truncated and
cannot be split. In commit 77008e1b2e ("mm/huge_memory: do not change
split_huge_page*() target order silently"), memory_failure() does not
handle it and pass -EBUSY to try_to_split_thp_page() directly.
try_to_split_thp_page() returns -EINVAL since -EBUSY becomes 0xfffffff0 as
new_order is unsigned int in __folio_split() and this large new_order is
rejected as an invalid input. The code does not cause a bug.
soft_offline_in_use_page() also uses min_order_for_split() but it always
passes 0 as new_order for split.
Fix it by making min_order_for_split() always return an order. When the
given folio is truncated, namely folio->mapping == NULL, return 0 and let
a subsequent split function handle the situation and return -EBUSY.
Add kernel-doc to min_order_for_split() to clarify its use.

can_split_folio() is just a refcount comparison, making sure only the
split caller holds an extra pin. Open code it with
folio_expected_ref_count() != folio_ref_count() - 1. For the extra_pins
used by folio_ref_freeze(), add folio_cache_ref_count() to calculate it.
Also replace folio_expected_ref_count() with folio_cache_ref_count() used
by folio_ref_unfreeze(), since they are returning the same values when a
folio is frozen and folio_cache_ref_count() does not have unnecessary
folio_mapcount() in its implementation.

Patch series "Improve folio split related functions", v4.
This patchset improves several folio split related functions to avoid
future misuse. The changes are:
1. Consolidated folio splittable checks by moving truncated folio check,
huge zero folio check, and writeback folio check into
folio_split_supported(). Changed the function return type. Renamed it
to folio_check_splittable() for clarification.
2. Replaced can_split_folio() with open coded folio_expected_ref_count()
and folio_ref_count() and introduced folio_cache_ref_count().
3. Changed min_order_for_split() to always return an order.
4. Fixed folio split stats counting.
Motivation
==========
This is based on Wei's observation[1] and solves several potential
issues:
1. Dereferencing NULL folio->mapping in try_folio_split_to_order() if it
is called on truncated folios.
2. Not handling of negative return value of min_order_for_split() in
mm/memory-failure.c
There is no bug in the current code.
This patch (of 4):
folio_split_supported() used in try_folio_split_to_order() requires
folio->mapping to be non NULL, but current try_folio_split_to_order() does
not check it. There is no issue in the current code, since
try_folio_split_to_order() is only used in truncate_inode_partial_folio(),
where folio->mapping is not NULL.
To prevent future misuse, move folio->mapping NULL check (i.e., folio is
truncated) into folio_split_supported(). Since folio->mapping NULL check
returns -EBUSY and folio_split_supported() == false means -EINVAL, change
folio_split_supported() return type from bool to int and return error
numbers accordingly. Rename folio_split_supported() to
folio_check_splittable() to match the return type change.
While at it, move is_huge_zero_folio() check and folio_test_writeback()
check into folio_check_splittable() and add kernel-doc.
Remove all warnings inside folio_check_splittable() and give warnings
in __folio_split() instead, so that bool warns parameter can be removed.

This series focuses on minor clean-ups and performance optimizations across
sysfs, documentation, debugfs, tracepoints, slab allocation, and GC.
Furthermore, it resolves several corner-case bugs caught by xfstests, as
well as issues related to 16KB page support and f2fs_enable_checkpoint.
Enhancement:
- wrap ASCII tables in literal blocks to fix LaTeX build
- optimize trace_f2fs_write_checkpoint with enums
- support to show curseg.next_blkoff in debugfs
- add a sysfs entry to show max open zones
- add fadvise tracepoint
- use global inline_xattr_slab instead of per-sb slab cache
- set default valid_thresh_ratio to 80 for zoned devices
- maintain one time GC mode is enabled during whole zoned GC cycle
Bug fix:
- ensure node page reads complete before f2fs_put_super() finishes
- fix to not account invalid blocks in get_left_section_blocks()
- revert summary entry count from 2048 to 512 in 16kb block support
- fix to detect recoverable inode during dryrun of find_fsync_dnodes()
- fix age extent cache insertion skip on counter overflow
- Add sanity checks before unlinking and loading inodes
- ensure minimum trim granularity accounts for all devices
- block cache/dio write during f2fs_enable_checkpoint()
- fix to propagate error from f2fs_enable_checkpoint()
- invalidate dentry cache on failed whiteout creation
- fix to avoid updating compression context during writeback
- fix to avoid updating zero-sized extent in extent cache
- fix to avoid potential deadlock

"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.

Core changes:
- Handle per-direction skew control in the generic pin config.
- Drop the pointless subsystem boilerplate banner message during
boot. Less noise in the console. It's available as debug message
if someone really want it.
New drivers:
- Samsung Exynos 8890 SoC support.
- 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
a century.
- Mediatek MT6878 SoC support.
- Qualcomm Glymur PMIC support (mostly just compatible strings).
- Qualcomm Kaanapali SoC TLMM support.
- Microchip pic64gx "gpio2" SoC support.
- Microchip Polarfire "iomux0" SoC support.
- CIX Semiconductors SKY1 SoC support.
- Rockchip RK3506 SoC support.
- Airhoa AN7583 chip support.
Improvements:
- Improvements for ST Microelectronics STM32 handling of skew
settings so input and output can have different skew settings.
- A whole bunch of device tree binding cleanups: Marvell Armada and
Berlin, Actions Semiconductor S700 and S900, Broadcom Northstar 2
(NS2), Bitmain BM1880 and Spreadtrum SC9860 are moved over to schema.
