Currently, the SND_SOC_DAPM_STREAM_START event is sent during pcm_prepare() but the SND_SOC_DAPM_STREAM_STOP event is sent only in dpcm_fe_dai_shutdown() after soc_pcm_close(). This results in an imbalance between when the DAPM widgets receive the PRE/POST_PMU/PMD events. So call snd_soc_dapm_stream_stop() in soc_pcm_hw_clean() before the snd_soc_pcm_component_hw_free() to keep the stream_stop DAPM event balanced with the stream_start event in soc_pm_prepare(). Also, in order to prevent duplicate DAPM stream events, remove the call for DAPM STREAM_START event in dpcm_fe_dai_prepare() and the call for DAPM STREAM_STOP event in dpcm_fe_dai_shutdown().
