From d0e3cce9144eb8bff0852531aadbe221addaa2d5 Mon Sep 17 00:00:00 2001 From: Manuel Lauss Date: Tue, 31 Jul 2012 14:42:27 +0200 Subject: ASoC: AC97 doesn't use regmap by default Since commit 38cbf9598feba97de9f9b43efa9153fd7c1a2ec9 ("ASoC: core: Try to use regmap if the driver doesn't set up any I/O") any ASoC codec which doesn't set codec::control_data is assumed to use regmap. That doesn't work with AC97 so this workaround sets the codec::control_data member to a random value to restore proper behaviour. Tested with WM9712.
