[PATCH 00/12] ASoC: Intel: updates for 6.10 - part5
by Pierre-Louis Bossart 01 May '24

01 May '24

This patchset corrects a couple of mistakes corrected, improves snd_soc_card allocation. The new functionality is mostly for SoundWire platforms, with new SKUs for Dell and Acer, and support for the Cirrus Logic bridge/sidecar amplifier topology.

[PATCH 0/8] ASoC: Intel: avs: PCM code cleanup
by Cezary Rojewski 01 May '24

01 May '24

A set of changes that aims to improve readability of cohesiveness of the pcm code for the avs-driver. Start off with a change that synchronizes DAI open/close - DAIs are started up in ascending order yet their shutdown does not follow the scheme - it is done in the ascending order too, rather than desceding one. This patch is a dependency for the next one in line. To align the HDAudio DAI startup/shutdown with the non-HDAudio equivalents, relocate the code from component to DAI. The reason above is a dependency stems from codec driver requirements - HDAudio code found in sound/pci/hda/ expects substream->runtime->private_data to point to a valid stream (HOST) pointer. With the hard part done, the follow up changes update the existing code to reduce it is complexity - removal of duplicates, renaming of ambiguous functions and adding new fields to DAI-data object so that the number of local variables and casts is reduced.

[PATCH 1/1] ALSA: aoa: soundbus: i2sbus: pcm: use 'time_left' variable with wait_for_completion_timeout()
by Wolfram Sang 01 May '24

01 May '24

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.
