ALSA: tea6330t: add mixer state restore helper

2026-04-08T07:55:03+00:00

The InterWave STB variant uses a TEA6330T mixer on its private I2C bus. The mixer state is cached in software, but there is no helper to push that register image back to hardware after system resume. Add a small restore helper that reapplies the cached TEA6330T register image to the device so board drivers can restore the external mixer state as part of their PM resume path. Take snd_i2c_lock() around the full device lookup and restore sequence so the bus device list traversal is also protected.

ALSA: tea6330t: move snd_tea6330t_detect() EXPORT_SYMBOL

2026-04-08T07:55:03+00:00

Move the remaining standalone snd_tea6330t_detect() EXPORT_SYMBOL() declaration next to its function definition so tea6330t.c follows the usual layout. No functional change intended.

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: i2c: Drop commented old debug prints

2024-08-08T05:47:24+00:00

There are quite a few commented-out debug prints that have never been used in the production code. Let's rip them off for code cleanness. Reviewed-by: Jaroslav Kysela Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20240807133452.9424-18-tiwai@suse.de

ALSA: i2c: tea6330t: Remove redundant initialization of variable err

2021-06-12T07:32:14+00:00

The variable err is being initialized with a value that is never read, it is being updated later on. The assignment is redundant and can be removed.

ALSA: i2c: Fix assignment in if condition

2021-06-09T15:30:37+00:00

ALSA I2C helper drivers contain a few assignments in if condition, which is a bad coding style that may confuse readers and occasionally lead to bugs. This patch is merely for coding-style fixes, no functional changes. Link: https://lore.kernel.org/r/20210608140540.17885-66-tiwai@suse.de Signed-off-by: Takashi Iwai

ALSA: i2c: Constify snd_kcontrol_new items

Most of snd_kcontrol_new definitions are read-only and passed as-is. Let's declare them as const for further optimization. There should be no functional changes by this patch. Link: https://lore.kernel.org/r/20200103081714.9560-35-tiwai@suse.de Signed-off-by: Takashi Iwai

ALSA: i2c: Remove empty init and exit

2018-08-03T14:11:43+00:00

For a sake of code simplification, remove the init and the exit entries that do nothing. Notes for readers: actually it's OK to remove *both* init and exit, but not OK to remove the exit entry. By removing only the exit while keeping init, the module becomes permanently loaded; i.e. you cannot unload it any longer! Signed-off-by: Takashi Iwai
