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: opl4: Convert to snd_seq bus probe mechanism

2025-12-14T10:08:09+00:00

The snd_seq bus got a dedicated probe function. Make use of that. This fixes a runtime warning about the driver needing to be converted to the bus probe method.

ALSA: opl4: Use guard() for spin locks

2025-09-01T11:53:34+00:00

Clean up the code using guard() for spin locks. Merely code refactoring, and no behavior change. Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20250829150026.6379-7-tiwai@suse.de

ALSA: opl4: Use guard() for mutex locks

2025-09-01T11:53:34+00:00

Replace the manual mutex lock/unlock pairs with guard() for code simplification. Only code refactoring, and no behavior change. Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20250829150026.6379-6-tiwai@suse.de

ALSA: opl4: Use safer strscpy() instead of strcpy()

2025-07-11T07:51:08+00:00

Use a safer function strscpy() instead of strcpy() for copying to arrays. Only idiomatic code replacement, and no functional changes. Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20250710100727.22653-7-tiwai@suse.de

ALSA: opl4: Use standard print API

2024-08-08T05:47:23+00:00

Use the standard print API with dev_*() instead of the old house-baked one. It gives better information and allows dynamically control of debug prints. Reviewed-by: Jaroslav Kysela Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20240807133452.9424-8-tiwai@suse.de

ALSA: drivers: Use -y instead of -objs in Makefile

2024-05-08T16:17:57+00:00

*-objs suffix is reserved rather for (user-space) host programs while usually *-y suffix is used for kernel drivers (although *-objs works for that purpose for now). Let's correct the old usages of *-objs in Makefiles.
