[ Upstream commit ff0045de4ee0288dec683690f66f2f369b7d3466 ]
RPM manipulation in hda_codec_probe_complete()'s error path is superfluous and leads to RPM usage count underflow if the build-controls operation fails.
hda_codec_probe_complete() is called in:
1) hda_codec_probe() for all non-HDMI codecs 2) in card->late_probe() for HDMI codecs
Error path for hda_codec_probe() takes care of bus' RPM already. For 2) if late_probe() fails, ASoC performs card cleanup what triggers hda_codec_remote() - same treatment is in 1).
