From e05854ddaa012f3369884acf61ec9953285404b4 Mon Sep 17 00:00:00 2001 From: Kyung-Kwee Ryu Date: Tue, 24 Apr 2012 18:01:48 +0100 Subject: [PATCH] ASoC: wm8994: Make sure we disable FLL bypass when stopping the FLL If FLL bypass is left enabled when we disable the CODEC then the output clock will be left running which consumes a small amount of additional current. Only enable bypass when there is an output.
