From 2a761cde31fddfe5e22f29bc5e241d597204e095 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 1 Nov 2011 15:19:23 +0000 Subject: [PATCH] ASoC: Start WM8962 FLL if SYSCLK is enabled Since we have code to automatically manage the start and stop of the FLL based on the SYSCLK widget if SYSCLK is already enabled and the FLL is configured then we need to start it up.
