[PATCH] ASoC: arizona: Wait for resume before enabling FLL

From: Richard Fitzgerald
Date: Thu Aug 25 2016 - 06:39:32 EST


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.
