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
