From 9313484238ca49fe5c7513dfcb36aaddcea8c298 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 20 Oct 2014 10:56:28 +0200 Subject: ASoC: ak4535: 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.
