Krzysztof Kozlowski cc3cb482c0 ASoC: codecs: wcd938x: handle deferred probe
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")
