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: isa: Add SPDX id lines to some files

2026-02-18T07:56:47+00:00

Add SPDX-License-Identifier lines to several files where they are missing, mostly in the sound/isa subdir. Use GPL-2.0 as the id.

ALSA: sb: 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: sb: Force to disable DMAs once when DMA mode is changed

2025-06-10T06:45:43+00:00

When the DMA mode is changed on the (still real!) SB AWE32 after playing a stream and closing, the previous DMA setup was still silently kept, and it can confuse the hardware, resulting in the unexpected noises. As a workaround, enforce the disablement of DMA setups when the DMA setup is changed by the kcontrol. https://bugzilla.kernel.org/show_bug.cgi?id=218185 Link: https://patch.msgid.link/20250610064322.26787-2-tiwai@suse.de Signed-off-by: Takashi Iwai

ALSA: sb: Don't allow changing the DMA mode during operations

2025-06-10T06:45:33+00:00

When a PCM stream is already running, one shouldn't change the DMA mode via kcontrol, which may screw up the hardware. Return -EBUSY instead. Link: https://bugzilla.kernel.org/show_bug.cgi?id=218185 Link: https://patch.msgid.link/20250610064322.26787-1-tiwai@suse.de Signed-off-by: Takashi Iwai
