[PATCH 02/20] ASoC: adau1701: Propagate register cache replay errors

[Pengpeng Hou]

adau1701_reset() marks the cache dirty after firmware and reset setup
but ignores regcache_sync().  The hw_params and component probe callers
return the helper status, so they can currently accept reset completion
while cached register state was not restored.

Return the cache replay error so those effective callers stop the
transition.

The issue was identified via static analysis and manually reviewed.

Fixes: 45405d58924f ("ASoC: adau1701: switch to direct regmap API usage")
