ASoC: sdw_utils: Check speaker component string allocation

2026-05-14T00:49:31+00:00

devm_kasprintf() can fail while building the temporary speaker component string. If that happens, spk_components is set to NULL, but the current code can still pass it to strlen() on a later loop iteration or after the loop when appending the speaker component list to card->components. Use NULL to represent the initial "no speaker components" state, and return -ENOMEM immediately if building spk_components fails.

ASoC: sdw_utils: Add quirk to ignore RT721 CODEC_MIC

2026-05-11T01:04:01+00:00

Add a quirk to skip the CODEC_MIC DAI when it is not present. This ensures PCH_DMIC is used as the fallback; otherwise, CODEC_MIC remains the default.

ASoC: sdw_utils: Add quirk to ignore RT712 CODEC_MIC

2026-05-11T01:04:00+00:00

Some devices do not use CODEC_MIC but use the host PCH_DMIC instead. Add a quirk to skip the CODEC_MIC DAI when it is not present in disco table, ensuring the correct capture device is used. If CODEC_MIC is present, it continues to be used as default.

ASoC: sdw_utils: cs42l43: allow spk component names to be combined

2026-04-22T15:00:10+00:00

Move handling of cs42l43-spk component string into SOF mechanism [1] which will allow it to be aggregated with other speakers. Likewise handle the cs35l56-bridge special case which should not be combined to keep compatibility with UCM.

Currently the index is 0. In theory, it will not change even if any other endpoint is not present. But to be consistent and avoid surprise, remove the index and let the machine driver match the codec name partially.
