treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

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 *".

MIPS: Alchemy: Remove bogus static/inline specifiers

2025-12-15T15:09:46+00:00

The recent io_remap_pfn_range() rework applied the static and inline
specifiers to the implementation of io_remap_pfn_range_pfn() on MIPS
Alchemy, mirroring the same change on other platforms. However, this
function is defined in a source file and that definition causes a
conflict with its declaration. Fix this by dropping the specifiers.

2025-12-06T01:29:04+00:00

Pull SoC driver updates from Arnd Bergmann:
 "This is the first half of the driver changes:

   - A treewide interface change to the "syscore" operations for power
     management, as a preparation for future Tegra specific changes

   - Reset controller updates with added drivers for LAN969x, eic770 and
     RZ/G3S SoCs

   - Protection of system controller registers on Renesas and Google
     SoCs, to prevent trivially triggering a system crash from e.g.
     debugfs access

   - soc_device identification updates on Nvidia, Exynos and Mediatek

   - debugfs support in the ST STM32 firewall driver

   - Minor updates for SoC drivers on AMD/Xilinx, Renesas, Allwinner, TI

   - Cleanups for memory controller support on Nvidia and Renesas"

mm: abstract io_remap_pfn_range() based on PFN

2025-11-17T01:28:12+00:00

The only instances in which we customise this function are ones in which we
customise the PFN used.

Instances where architectures were not passing the pgprot value through
pgprot_decrypted() are ones where pgprot_decrypted() was a no-op anyway, so
we can simply always pass pgprot through this function.

Use this fact to simplify the use of io_remap_pfn_range(), by abstracting
the PFN via io_remap_pfn_range_pfn() and using this instead of providing a
general io_remap_pfn_range() function per-architecture.

syscore: Pass context data to callbacks

2025-11-14T09:01:52+00:00

Several drivers can benefit from registering per-instance data along
with the syscore operations. To achieve this, move the modifiable fields
out of the syscore_ops structure and into a separate struct syscore that
can be registered with the framework. Add a void * driver data field for
drivers to store contextual data that will be passed to the syscore ops.

MIPS: Alchemy: convert from round_rate() to determine_rate()

2025-08-29T20:34:29+00:00

The round_rate() clk ops is deprecated, so migrate this driver from
round_rate() to determine_rate() using the Coccinelle semantic patch
appended to the "under-the-cut" portion of the patch.

Note that prior to running Coccinelle, alchemy_clk_aux_roundr() was
renamed to alchemy_clk_aux_round_rate(). A few minor style cleanups
were also done by hand.

treewide: rename GPIO set callbacks back to their original names

2025-08-07T08:07:06+00:00

The conversion of all GPIO drivers to using the .set_rv() and
.set_multiple_rv() callbacks from struct gpio_chip (which - unlike their
predecessors - return an integer and allow the controller drivers to
indicate failures to users) is now complete and the legacy ones have
been removed. Rename the new callbacks back to their original names in
one sweeping change.
