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().

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
