Subject: [PATCH 1/2] ASoC: tlv320aic23: Clear TLV320AIC23_MS_MASTER bit for slave mode
Date: Thu, 27 Oct 2011 16:35:49 +0800	[thread overview]
Message-ID: <1319704549.2673.2.camel@phoenix> (raw)

According to the datasheet:

Digital Audio Interface Format (07h) register:
BIT6:	Master/slave mode
	0: Slave
	1: Master

Current code sets TLV320AIC23_MS_MASTER bit for master mode,
but does not clear it for slave mode.
