From 98d3088e534a2a61f6690b5426909b0c3b57a785 Mon Sep 17 00:00:00 2001 From: Mark Brown <broonie@opensource.wolfsonmicro.com> Date: Wed, 1 Aug 2012 20:05:47 +0100 Subject: [PATCH] ASoC: core: Fix check before defaulting to regmap Check if the chip has provided a write operation (which is mandatory for I/O) rather than looking for control data as some of the MFDs use a global for this. Also skip the attempt if there's no regmap available by device in case things get confused by the attempt to default.
