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: compress_offload: Add 64-bit safe timestamp infrastructure

2025-09-08T07:33:24+00:00

The copied_total field in struct snd_compr_tstamp is a 32-bit value that can overflow on long-running high-bitrate streams, leading to incorrect calculations for buffer availablility. This patch adds a 64-bit safe timestamping mechanism. A new UAPI struct, snd_compr_tstamp64, is added which uses 64-bit types for byte counters. The relevant ops structures across the ASoC and core compress code are updated to use this new struct. ASoC drivers are updated to use u64 counters. Internal timestamps being u64 now, a compatibility function is added to convert the 64-bit timestamp back to the 32-bit format for legacy ioctl callers.

ASoC: sprd: Standardize ASoC menu

2025-06-24T00:01:21+00:00

Current Kconfig menu at [ALSA for SoC audio support] has no rules. So, some venders are using menu style, some venders are listed each drivers on top page, etc. It is difficult to find target vender and/or drivers because it is very random. Let's standardize ASoC menu Signed-off-by: Kuninori Morimoto Link: https://patch.msgid.link/87jz5hzqe1.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown

ASoC: Switch back to struct platform_driver::remove()

2024-09-09T17:26:49+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all drivers below sound/soc to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

ASoC: sprd: Use -y instead of -objs in Makefile

2024-05-08T02:39:32+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. Signed-off-by: Takashi Iwai Link: https://lore.kernel.org/r/20240507155540.24815-27-tiwai@suse.de Signed-off-by: Mark Brown

ASoC: sprd: sprd-mcdt: Convert to platform remove callback returning void

2023-03-20T13:09:02+00:00

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
