Subject: ASoC: wm8974: set cache type for regmap
From: Mans Rullgard <mans@xxxxxxxxx>
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.
