[PATCH 6.7 154/309] ASoC: codecs: wcd938x: handle deferred probe

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.7-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>

commit 086df711d9b886194481b4fbe525eb43e9ae7403 upstream.

WCD938x sound codec driver ignores return status of getting regulators
and returns EINVAL instead of EPROBE_DEFER.  If regulator provider
probes after the codec, system is left without probed audio:

  wcd938x_codec audio-codec: wcd938x_probe: Fail to obtain platform data
  wcd938x_codec: probe of audio-codec failed with error -22
