From 8ecb5344fd6409c500c9d5757c3a7130d3d7db5b Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Sat, 31 Aug 2013 13:51:38 +0100 Subject: [PATCH 1/4] ASoC: cq93vc: Don't use control data for core driver data The platform data is being used to obtain the core driver data for the device (which is a bit of an abuse but not the issue at hand) so reference it directly in order to support refactoring to use regmap.
