ALSA: aoa: onyx: Update IEC958 sample-rate status for PCM playback

2026-04-06T08:41:00+00:00

onyx_prepare() accepts 32/44.1/48 kHz PCM playback, but it leaves the Onyx IEC958 sample-rate status bits at the driver's initial 44.1 kHz setting in DIG_INFO3. As a result, 32 kHz and 48 kHz PCM streams advertise a stale IEC958 sample rate unless userspace rewrites IEC958 Playback Default first. Update only the consumer sample-frequency bits in DIG_INFO3 from the PCM runtime during prepare, resolving the long-standing FIXME in the PCM playback path while leaving the other user-controlled IEC958 status bits unchanged. Mark IEC958 Playback Default as volatile as well, since prepare() now changes the exposed register contents outside the control put callback.

ALSA: aoa: i2sbus: clear stale prepared state

2026-04-01T07:58:37+00:00

The i2sbus PCM code uses pi->active to constrain the sibling stream to an already prepared duplex format and rate in i2sbus_pcm_open(). That state is set from i2sbus_pcm_prepare(), but the current code only clears it on close. As a result, the sibling stream can inherit stale constraints after the prepared state has been torn down. Clear pi->active when hw_params() or hw_free() tears down the prepared state, and set it again only after prepare succeeds. Replace the stale FIXME in the duplex constraint comment with a description of the current driver behavior: i2sbus still programs a single shared transport configuration for both directions, so mixed formats are not supported in duplex mode.

ALSA: aoa: i2sbus: fix OF node lifetime handling

2026-03-30T07:35:56+00:00

i2sbus_add_dev() keeps the matched "sound" child pointer after for_each_child_of_node() has dropped the iterator reference. Take an extra reference before saving that node and drop it after the layout-id/device-id lookup is complete. The function also stores np in dev->sound.ofdev.dev.of_node without taking a reference for the embedded soundbus device. Since i2sbus overrides the embedded platform device release callback, balance that reference explicitly in the local error path and in i2sbus_release_dev().

ALSA: aoa: Skip devices with no codecs in i2sbus_resume()

2026-03-10T17:20:37+00:00

In i2sbus_resume(), skip devices with an empty codec list, which avoids using an uninitialized 'sysclock_factor' in the 32-bit format path in i2sbus_pcm_prepare(). In i2sbus_pcm_prepare(), replace two list_for_each_entry() loops with a single list_first_entry() now that the codec list is guaranteed to be non-empty by all callers.

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

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
