ASoC: SDCA: Add allocation failure check for Entity name

2026-03-03T14:23:32Z

Currently find_sdca_entity_iot() can allocate a string for the Entity name but it doesn't check if that allocation succeeded. Add the missing NULL check after the allocation.

ASoC: SDCA: Fix comments for sdca_irq_request()

2026-02-26T16:57:37Z

The kernel-doc comments for sdca_irq_request() contained some typos that lead to build warnings with W=1. Let's correct them.

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

ASoC: SDCA: Limit values user can write to Selected Mode

2026-02-04T14:10:51Z

Prevent the user from both updating the Selected Mode control whilst the jack is not present, and from writing values that don't correspond to a valid jack type (Unknown, in progress, etc.).

ASoC: SDCA: Add regmap defaults for specification defined values

2026-02-04T14:10:50Z

Some of the SDCA Controls have a defined reset value in the specification. Update the parsing to add these specification defined values into the regmap defaults array. This will reduce the number of registers that are synchronised on a cache sync.

ASoC: SDCA: Rearrange FDL file messages

2026-02-04T14:10:49Z

It is helpful to have something in the log showing which firmware file was loaded by the driver. Update the existing FDL disk file debug statement to just note that a disk file rather than ACPI file was used, and add a new info printk that prints out the details of the loaded file regardless of where that file came from. Likewise, sometimes it is useful to get a message if the file-sets list is missing, although this isn't technically an error so make it a debug.

ASoC: SDCA: Still process most of the jack detect if control is missing

2026-02-04T14:10:48Z

DAPM creates its controls very late in the card creation, so there is no call into the driver after the controls are created. This means the jack IRQs can't be guaranteed to be registered after the ALSA controls are available. If a jack IRQ is received before the controls are available, currently the driver does not update the Selected Mode as it is required by the specification to do. If the ALSA controls are not available update the Selected Mode directly rather than going through the ALSA control. The ALSA control should pick up the state once it is created.

ASoC: SDCA: Handle volatile controls correctly

2026-02-04T14:10:47Z

There are very few volatile controls in SDCA that are exported as ALSA controls, typically Detected Mode is the only common one. However, the current code does not resume the device when these ALSA controls are accessed, which will result in the read/write failing. Add a new wrapper specifically for volatile controls that will do the required pm_runtime operations before accessing the register.
