Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

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

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: vx: 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/20250829150026.6379-8-tiwai@suse.de

ALSA: vx: 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. Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20250710100727.22653-13-tiwai@suse.de

ALSA: vx_core: 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. The commented old debug prints are dropped, too. Reviewed-by: Jaroslav Kysela Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20240807133452.9424-12-tiwai@suse.de

ALSA: vx_core: Drop unused dev field

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

The vx_core.dev field has never been set but referred incorrectly at firmware loading. Pass the proper device pointer from card->dev at request_firmware(), and drop the unused dev field from vx_core, too.

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.

ALSA: vx: Drop superfluous GFP setup

2022-08-24T06:00:26+00:00

The extra setup with GFP_DMA32 is superfluous for this driver. The whole operation is a simple copy loop, and there is no memory address restriction at all. Drop the useless GFP setup. Link: https://lore.kernel.org/r/20220823115740.14123-2-tiwai@suse.de Signed-off-by: Takashi Iwai
