Subject[PATCH 3.13 111/149] ASoC: 88pm860: Fix IO setup
Date
3.13-stable review patch.  If anyone has any objections, please let me know.

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

From: Lars-Peter Clausen <lars@metafoo.de>

commit 8eeb5c15131d7b5061c10423eda3ae4c68db4eaf upstream.

The 88pm860 is a MFD device and the CODEC driver is using the regmap struct of
the parent device, hence automatic IO setup will not work and we need to
manually call snd_soc_codec_set_cache_io(). The issue was introduced in commit
f9ded3b2e7 ("ASoC: 88pm860x: Use regmap for I/O").

Fixes: f9ded3b2e7 ("ASoC: 88pm860x: Use regmap for I/O").
