Subject[ 03/11] ASoC: wm8903: Fix the bypass to HP/LINEOUT when no DAC or ADC is running
Date
3.0-stable review patch.  If anyone has any objections, please let me know.

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

From: Alban Bedel <alban.bedel@avionic-design.de>

commit f1ca493b0b5e8f42d3b2dc8877860db2983f47b6 upstream.

The Charge Pump needs the DSP clock to work properly, without it the
bypass to HP/LINEOUT is not working properly. This requirement is not
mentioned in the datasheet but has been confirmed by Mark Brown from
Wolfson.
