From 5c9dc0898f343473efa3056fff9d5a9fbd577272 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Sun, 23 Nov 2014 13:47:51 +0100 Subject: [PATCH] ASoC: alc5632: Cleanup 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.
