From: Johan Hovold <johan+linaro@xxxxxxxxxx>
commit 798590cc7d3c2b5f3a7548d96dd4d8a081c1bc39 upstream.
Make sure to release allocated MBHC resources also on component remove.
This is specifically needed to allow probe deferrals of the sound card
which otherwise fails when reprobing the codec component.
Fixes: 9fb9b1690f0b ("ASoC: codecs: wcd934x: add mbhc support")
