From 63d19e0693668de5ce46b5f0f948645bf43b546b Mon Sep 17 00:00:00 2001 From: Richard Fitzgerald Date: Thu, 25 Aug 2016 11:39:32 +0100 Subject: [PATCH] ASoC: arizona: Wait for resume before enabling FLL When enabling an FLL use pm_runtime_get_sync() instead of pm_runtime_get() to ensure that all the register settings have been written out and the codec is powered-up before we write the enable bit.
