From 5e201204474d4760bb496b77b01b8e143cdaf20e Mon Sep 17 00:00:00 2001 From: Mans Rullgard Date: Fri, 11 Dec 2015 11:27:08 +0000 Subject: [PATCH] ASoC: wm8974: set cache type for regmap commit 1ea5998afe903384ddc16391d4c023cd4c867bea upstream. Attempting to use this codec driver triggers a BUG() in regcache_sync() since no cache type is set. The register map of this device is fairly small and has few holes so a flat cache is suitable.
