Subject: [PATCH RFT 2/2] pinctrl: dove: Checking valid config in dove_audio1_ctrl_set

From: [email-masked] (Axel Lin)
Date: Sun, 11 Nov 2012 21:46:09 +0800

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.
