Merge tag 'gpio-fixes-for-v7.0-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio fixes from Bartosz Golaszewski:

- fix memory leaks in shared GPIO management

- normalize the return values of gpio_chip::get() in GPIO core on
behalf of drivers that return invalid values (this is done because
adding stricter sanitization of callback retvals led to breakages in
existing users, we'll revert that once all are fixed)

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

This converts some of the visually simpler cases that have been split
over multiple lines. I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.

Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script. I probably had made it a bit _too_ trivial.

So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.

The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

Convert 'alloc_flex' family to use the new default GFP_KERNEL argument

This is the exact same thing as the 'alloc_obj()' version, only much
smaller because there are a lot fewer users of the *alloc_flex()
interface.

As with alloc_obj() version, this was done entirely with mindless brute
force, using the same script, except using 'flex' in the pattern rather
than 'objs*'.

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

This was done entirely with mindless brute force, using

git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

Merge tag 'kmalloc_obj-treewide-v7.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull kmalloc_obj conversion from Kees Cook:
"This does the tree-wide conversion to kmalloc_obj() and friends using
coccinelle, with a subsequent small manual cleanup of whitespace
alignment that coccinelle does not handle.

This uncovered a clang bug in __builtin_counted_by_ref(), so the
conversion is preceded by disabling that for current versions of
clang. The imminent clang 22.1 release has the fix.

I've done allmodconfig build tests for x86_64, arm64, i386, and arm. I
did defconfig builds for alpha, m68k, mips, parisc, powerpc, riscv,
s390, sparc, sh, arc, csky, xtensa, hexagon, and openrisc"

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)

Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

spi: Octal DTR support

This series adds support for 8D-8D-8D in SPI NAND, which can already be
leveraged without any SPI changes as controllers already have this
support for some SPI NOR devices.

Among the few spi-mem patches, they are needed for building the SPI NAND
changes (especially the ODTR introduction at the end) and therefore an
immutable tag will be needed for merging in the MTD tree (unless all the
series goes through MTD directly ofc).

Pull gpio updates from Bartosz Golaszewski:
"There are two new drivers and some changes to GPIO core but mostly
just GPIO driver updates across a wide array of files, adding support
for new models as well as various refactoring changes. Nothing
controversial and everything has spent a good measure of time in
linux-next.

GPIOLIB core:
- shrink the GPIO bus driver stub code
- rework software node support for "undefined" software nodes
- provide and use devm_fwnode_gpiod_get_optional()
- only compile the OF quirk for MT2701 when needed

New drivers:
- add the GPIO driver for ROHM bd72720
- add the gpio-line-mux driver providing 1-to-many mapping for a
single real GPIO

Driver changes:
- refactor gpio-pca9570: use lock guard, add missing headers, use
devres consistently
- add support for a new model (G7 Aspeed sgpiom) to the aspeed-sgpio
driver along with some prerequisite refactoring
- use device_get_match_data() where applicable and save some lines
- add support for more models to gpio-cadence
- add the compatible property to reset-gpio and use it in shared GPIO
management
- drop unnecessary use of irqd_get_trigger_type() in gpio-max77759
- add support for a new variant to gpio-pca953x
- extend build coverage with COMPILE_TEST for more drivers
- constify configfs structures in gpio-sim and gpio-virtuser
- add support for the K3 SoC to gpio-spacemit
- implement the missing .get_direction() callback in gpio-max77620
- add support for Tegra264 to gpio-tegra186
- drop unneeded MODULE_ALIAS() from gpio-menz127

DT bindings:
- document support for the opencores GPIO controller in gpio-mmio
- document new variants for gpio-pca953x

Documentation:
- extensively describe interrupt source detection for gpio-pca953x
and add more models to the list of supported variants"

ASoC: Updates for v7.0

This release is almost all abut driers, there's very little core work
here, although some of that driver work is in more generic areas like
SDCA and SOF:

- Generic SDCA support for reporting jack events.
- Continuing platform support, cleanup and feature improements for the
AMD, Intel, Qualcomm and SOF code.
- Platform description improvements for the Cirrus drivers.
- Support for NXP i.MX952, Realtek RT1320 and RT5575, and Sophogo
CV1800B.

We also pulled in one small SPI API update and some more substantial
regmap work (cache description improvements) for use in drivers.

spi: aspeed: Improve handling of shared SPI

Merge series from Chin-Ting Kuo <chin-ting_kuo@aspeedtech.com>:

This patch series improves handling of SPI controllers that are
shared by spi-mem devices and other SPI peripherals.

The primary goal of this series is to support non-spi-mem devices in
the ASPEED FMC/SPI controller driver. It also addresses an issue in
the spi-mem framework observed when different types of SPI devices
operate concurrently on the same controller, ensuring that spi-mem
operations are properly serialized.
