treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

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 *". Signed-off-by: Kees Cook

ASoC: amd: ps: Propagate the PCI subsystem Vendor and Device IDs

ASoC: amd: ps: fix for soundwire failures during hibernation exit sequence

2025-06-23T13:20:29Z

During the hibernate entry sequence, ACP registers will be reset to default values and acp ip will be completely powered off including acp SoundWire pads. During resume sequence, if acp SoundWire pad keeper enable register is not restored along with pad pulldown control register value, then SoundWire manager links won't be powered on correctly results in peripheral register access failures and completely audio function is broken. Add code to store the acp SoundWire pad keeper enable register and acp pad pulldown ctrl register values before entering into suspend state and restore the register values during resume sequence based on condition check for acp SoundWire pad keeper enable register for ACP6.3, ACP7.0 & ACP7.1 platforms.

ASoC: amd: ps: fix for irq handler return status

2025-04-30T23:22:36Z

If any Soundwire manager interrupt is reported, and wake interrupt is not reported, in this scenario irq_flag will be set to zero, which results in interrupt handler return status as IRQ_NONE. Add new irq flag 'wake_irq_flag' check for SoundWire wake interrupt handling to fix incorrect irq handling return status.

ASoC: amd: Convert to RUNTIME_PM_OPS() & co

2025-03-17T10:15:04Z

Use the newer RUNTIME_PM_OPS() and SYSTEM_SLEEP_PM_OPS() macros instead of SET_RUNTIME_PM_OPS() and SET_SYSTEM_SLEEP_PM_OPS() together with pm_ptr(), which allows us dropping ugly __maybe_unused attributes. This optimizes slightly when CONFIG_PM is disabled, too.
