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

2026-05-07T04:09:45+00:00

[ Upstream commit fd7df93013c5118812e63a52635dc6c3a805a1de ] 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.

ALSA: aoa: i2sbus: clear stale prepared state

2026-05-07T04:09:45+00:00

[ Upstream commit 5ed060d5491597490fb53ec69da3edc4b1e8c165 ] 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

2026-05-07T04:09:29+00:00

commit 4ec93f070eda6b765b62efcaed9241c3b3b0b6ad upstream. 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: Drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-09-20T15:44:52+00:00

These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own.

ALSA: aoa: Use -y instead of -objs in Makefile

2024-05-08T16:18:08+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.

ALSA: aoa: soundbus: i2sbus: pcm: use 'time_left' variable with wait_for_completion_timeout()

2024-05-08T16:15:06+00:00

There is a confusing pattern in the kernel to use a variable named 'timeout' to store the result of wait_for_completion_timeout() causing patterns like: timeout = wait_for_completion_timeout(...) if (!timeout) return -ETIMEDOUT; with all kinds of permutations. Use 'time_left' as a variable to make the code self explaining. Fix to the proper variable type 'unsigned long' while here.

2024-04-05T06:48:12+00:00

ASoC: Fixes for v6.9 A relatively large set of fixes here, the biggest piece of it is a series correcting some problems with the delay reporting for Intel SOF cards but there's a bunch of other things. Everything here is driver specific except for a fix in the core for an issue with sign extension handling volume controls.

ALSA: aoa: avoid false-positive format truncation warning

2024-03-27T09:53:37+00:00

clang warns about what it interprets as a truncated snprintf: sound/aoa/soundbus/i2sbus/core.c:171:6: error: 'snprintf' will always be truncated; specified size is 6, but format string expands to at least 7 [-Werror,-Wformat-truncation-non-kprintf] The actual problem here is that it does not understand the special %pOFn format string and assumes that it is a pointer followed by the string "OFn", which would indeed not fit. Slightly increasing the size of the buffer to its natural alignment avoids the warning, as it is now long enough for the correct and the incorrect interprations.
