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

2026-02-21T09:02:28Z

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

ALSA: dummy: Use guard() for spin locks

2025-09-01T11:53:34Z

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/20250829150026.6379-9-tiwai@suse.de

ALSA: dummy: Replace deprecated strcpy() with strscpy()

2025-06-30T12:08:32Z

strcpy() is deprecated; use strscpy() instead. No functional changes intended. Link: https://github.com/KSPP/linux/issues/88 Signed-off-by: Thorsten Blum Link: https://patch.msgid.link/20250630110945.2225-2-thorsten.blum@linux.dev Signed-off-by: Takashi Iwai

treewide, timers: Rename from_timer() to timer_container_of()

2025-06-08T07:07:37Z

Move this API to the canonical timer_*() namespace. [ tglx: Redone against pre rc1 ] Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner Link: https://lore.kernel.org/all/aB2X0jCKQO56WdMt@gmail.com

treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12Z

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

ALSA: Switch to use hrtimer_setup()

2025-02-10T08:26:31Z

hrtimer_setup() takes the callback function pointer as argument and initializes the timer completely. Replace hrtimer_init() and the open coded initialization of hrtimer::function with the new setup mechanism. Patch was created by using Coccinelle.

ALSA: dummy: Use standard print API

2024-08-08T05:47:23Z

Use pr_*() macro instead of open-coded printk() just for code simplification. Reviewed-by: Jaroslav Kysela Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20240807133452.9424-14-tiwai@suse.de

ALSA: dummy: Replace with DEFINE_SIPMLE_DEV_PM_OPS()

2024-02-12T10:50:24Z

Use the new DEFINE_SIMPLE_DEV_PM_OPS() instead of SIMPLE_DEV_PM_OPS() for code-simplification. We need no longer CONFIG_PM_SLEEP ifdefs. Just a cleanup, no functional changes.

ALSA: dummy: Convert to generic PCM copy ops

2023-08-18T10:18:17Z

This patch converts the dummy driver code to use the new unified PCM copy callback. As dummy driver doesn't do anything in the callback, it's just a simple replacement. Reviewed-by: Andy Shevchenko Link: https://lore.kernel.org/r/20230815190136.8987-5-tiwai@suse.de Signed-off-by: Takashi Iwai
