* snd_pcm_period_elapsed_under_stream_lock() - update the status of runtime for the next period
* under acquired lock of PCM substream.
* @substream: the instance of pcm substream.
*
* This function is called from the interrupt handler when the
* PCM has processed the period size. It will update the current
* pointer, wake up sleepers, etc.
* This function is called when the batch of audio data frames as the same size as the period of
* buffer is already processed in audio data transmission.
*
* Even if more than one periods have elapsed since the last call, you
* have to call this only once.
* The call of function updates the status of runtime with the latest position of audio data
* transmission, checks overrun and underrun over buffer, awaken user processes from waiting for
* available audio data frames, sampling audio timestamp, and performs stop or drain the PCM
* substream according to configured threshold.
*
* The function is intended to use for the case that PCM driver operates audio data frames under
* acquired lock of PCM substream; e.g. in callback of any operation of &snd_pcm_ops in process
* context. In any interrupt context, it's preferrable to use ``snd_pcm_period_elapsed()`` instead
* since lock of PCM substream should be acquired in advance.
*
* Developer should pay enough attention that some callbacks in &snd_pcm_ops are done by the call of
* function:
*
* - .pointer - to retrieve current position of audio data transmission by frame count or XRUN state.
* - .trigger - with SNDRV_PCM_TRIGGER_STOP at XRUN or DRAINING state.
* - .get_time_info - to retrieve audio time stamp if needed.
*
* Even if more than one periods have elapsed since the last call, you have to call this only once.
