[PATCH 2/5] ASoC: codecs/jz4770: Reset interrupt flags in bias PREPARE

From: Paul Cercueil
Date: Mon Dec 07 2020 - 07:55:39 EST


From: Christophe Branchereau <cbranchereau@xxxxxxxxx>

In case a poll for RUP times out, we might be left with some IRQ flags
that should be cleared before the next power on.
