The pin updates in this driver look like they are intended to be done atomically, update to do so. It looks like these were originally locked with the CODEC mutex and not updated since the patch "ASoC: dapm: Use DAPM mutex for DAPM ops instead of codec mutex", so remove the original CODEC mutex locking as well.
