From 0a87a6e1c09c3b93d91bf65809e79cf6cf358785 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Sun, 23 Nov 2014 13:37:33 +0100 Subject: [PATCH] ASoC: wm8960: Cleanup manual bias level transitions Set the CODEC driver's suspend_bias_off flag rather than manually going to SND_SOC_BIAS_OFF in suspend and SND_SOC_BIAS_STANDBY in resume. This makes the code a bit shorter and cleaner. Since the ASoC core now takes care of setting the bias level to SND_SOC_BIAS_OFF when removing the CODEC there is no need to do it manually anymore either. The manual transition to SND_SOC_BIAS_STANDBY at the end of CODEC probe() can also be removed as the core will automatically do this after the CODEC has been probed.
