treewide: refresh kmalloc_obj() conversions

2026-09-05T04:37:00+00:00

This is another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci This catches both the set of kmalloc() uses added since the first kmalloc_obj() conversions in v7.0 and adds a large group missed in the first pass due to Coccinelle not interacting well with the cleanup.h scoped_...() family of macros[1]. I worked around this with spatch's "--macro-file" argument to a file with all the scoped_...() macros mapped to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control flow indicator I could find. Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc, riscv, and s390 with no new warnings.

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 *". Signed-off-by: Kees Cook

ASoC: SOF: Use guard()/scoped_guard() for mutex locks where it makes sense

2026-01-12T11:21:24+00:00

Replace the manual mutex lock/unlock pairs with guard()/scoped_guard(). Only code refactoring, and no behavior change.

ASoC: SOF: sof-client: Add support for on-demand DSP boot

2025-12-15T14:07:42+00:00

With the introduction of on-demand DSP boot the rpm status not necessary tells that the DSP firmware is booted up. Introduce the sof_client_boot_dsp() which can be used to make sure that the DSP is booted and it can handle IPCs. Update the client drivers to use the new function where it is expected that the DSP is booted up.

ASoC: SOF: sof-client: Introduce sof_client_dev_entry structure

2025-08-29T11:34:26+00:00

Introduce a new internal structure for wrapping the sof_client_dev and move members away from the client visible struct that they must not access, let alone see (sdev and the list). The changes are mechanical in nature and contained within sof-client core code, no functional change or change in behavior is introduced.

module: Convert symbol namespace to string literal

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.
