Subject: [PATCH 1/2] ASoC: wm8711: Fix wrong mask for setting input audio data bit length select
Date: Fri, 28 Oct 2011 11:08:01 +0800 [thread overview]
Message-ID: <1319771281.3944.1.camel@phoenix> (raw)
The Input Audio Data Bit Length Select is controlled by BIT[3:2] of
WM8711_IFACE(07h) register.
Current code incorrectly masks BIT[1:0] which is for Audio Data Format Select.
