From d66b8537b30fbaf79e0f467fa6b7e1a2191cba83 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Tue, 22 Nov 2011 17:17:23 +0100 Subject: ASoC: cs4720: use snd_soc_cache_sync() Replace the manual register restore mechanism in cs4270.c and call the generic snd_soc_cache_sync() handler instead. This factors code out in favour of core facilities and also fixes a bus confusion that is most probably caused by intermixing i2c-regmap functions and i2c_smbus_* accessors.
