--------------------------------

[ Upstream commit 0a0342ed ]

On probe of the ASoC component, the device is reset but the regcache is
retained. This means the regcache gets out of sync if the codec is
rebound to a sound card for a second time. Fix it by reinitializing the
regcache to defaults after the device is reset.
