    ASoC: dapm: Fix SUSPEND -> OFF bias sequence · ce85a4d7
    Lars-Peter Clausen 提交于
    Currently when the DAPM context bias level is SUSPEND and the target bias level
    is OFF dapm_pre_sequence_async() will first transition to PREPARE and
    dapm_post_sequence_async() will then transition back from PREPARE to STANDBY and
    then to OFF.
    
    This patch makes sure that dapm_pre_sequence_async() only transitions to PREPARE
    when either going to ON or away from ON. This avoids the extra unnecessary
    transitions.
