[alsa-devel] [PATCH] ASoC: tlv320aic31xx: place codec into reset state initially

[Peter S. Housel]

Previously the driver would only place the TLV320AIC31XX into reset
using the gpio reset line when at least one of the power supply
regulators was disabled, so that if these supplies were always enabled
no reset would ever occur. This change resets the codec state at probe
time so that the initial register cache values are correct.
