Subject: [PATCH RFT 2/2] pinctrl: dove: Checking valid config in dove_audio1_ctrl_set
Date: Sun, 11 Nov 2012 21:46:09 +0800	[thread overview]
Message-ID: <1352641569.3113.2.camel@phoenix> (raw)
In-Reply-To: <1352641495.3113.1.camel@phoenix>

Move the code checking valid config to dove_audio1_ctrl_set(), this ensures we
always set valid config. And then dove_audio1_ctrl_get() always returns correct
config.
