ALSA: sc6000: Keep the programmed board state in card-private data

2026-05-23T11:08:55+00:00

[ Upstream commit fb79bf127ac2577b4876132da6dba768018aad4c ] The driver may auto-select IRQ and DMA resources at probe time, but sc6000_init_board() still derives the SC-6000 soft configuration from the module parameter arrays. When irq=auto or dma=auto is used, the codec is created with the selected resources while the board is programmed with the unresolved values. Store the mapped ports and generated SC-6000 board configuration in card-private data, build that configuration from the live probe results instead of the raw module parameters, and keep the probe-time board programming in a shared helper. This fixes the resource-programming mismatch and leaves the driver with a stable board-state block that can be reused by suspend/resume.

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

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: wavefront: Fix integer overflow in sample size validation

2025-11-06T10:03:28+00:00

The wavefront_send_sample() function has an integer overflow issue when validating sample size. The header->size field is u32 but gets cast to int for comparison with dev->freemem Fix by using unsigned comparison to avoid integer overflow.
