[PATCH 3.2 122/185] ASoC: wm8731: fix dsp mode configuration

From: Ben Hutchings
Date: Sat Dec 28 2013 - 22:05:56 EST


3.2.54-rc1 review patch. If anyone has any objections, please let me know.

------------------

From: Bo Shen <voice.shen@xxxxxxxxx>

commit b4af6ef99a60c5b56df137d7accd81ba1ee1254e upstream.

According to WM8731 "PD, Rev 4.9 October 2012" datasheet, when it
works in DSP mode A, LRP = 1, while works in DSP mode B, LRP = 0.
So, fix LRP for DSP mode as the datesheet specification.
