6.6-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
Fixes: 16572522aece ("ASoC: codecs: wcd938x-sdw: add SoundWire driver")
