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

This was done entirely with mindless brute force, using git grep -l '\

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

ALSA: hda: Relax __free() variable declarations

2025-12-17T09:08:30+00:00

We used to have a variable declaration with __free() initialized with NULL. This was to keep the old coding style rule, but recently it's relaxed and rather recommends to follow the new rule to declare in place of use for __free() -- which avoids potential deadlocks or UAFs with nested cleanups. Although the current code has no bug, per se, let's follow the new standard and move the declaration to the place of assignment (or directly assign the allocated result) instead of NULL initializations.

ALSA: hda/generic: Use auto cleanup for temporary buffers

2025-08-29T09:52:15+00:00

The release of temporary kmalloced buffers can be nicely handled via the standard __free(kfree). Only code refactoring, and no behavior change. Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20250827072916.31933-22-tiwai@suse.de

ALSA: hda: Use safer strscpy() instead of strcpy()

Use a safer function strscpy() instead of strcpy() for copying to arrays. Only idiomatic code replacement, and no functional changes. Link: https://patch.msgid.link/20250711083051.18759-1-tiwai@suse.de Signed-off-by: Takashi Iwai

ALSA: hda: Drop old codec binding method

2025-07-11T07:55:38+00:00

Now that all patch_ops usage have been converted to the new hda_codec_ops probe, we can drop patch_ops from the hda_codec, together with the calls of patch_ops callbacks. The hda_codec_ops.free callback is removed as all have been replaced with the new remove callback. Also, correct comments mentioning "patch"; it's replaced with "codec driver".

ALSA: hda: Move codec drivers into sound/hda/codecs directory

2025-07-11T07:55:37+00:00

Now move the all remaining codec drivers from sound/pci/hda to sound/hda/codecs subdirectory. Some drivers are put under the further vendor subdirectory, and the vendor helper code (*_helper.c) are put under helpers subdirectory. Also the sub-codec drivers are moved under a different subdirectory, sound/hda/codecs/sub-codecs, for distinguishing from the main HD-audio codec drivers. The prefix patch_ and hda_ as well as the suffix _helper are dropped from file names as they are mostly superfluous. No functional changes but just file path shuffling.
