From 1fb8510cdb5b7befe8a59f533c7fc12ef0dac73e Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 7 Nov 2014 17:08:28 +0100 Subject: ALSA: pcm: Add snd_pcm_stop_xrun() helper Add a new helper function snd_pcm_stop_xrun() to the standard sequnce lock/snd_pcm_stop(XRUN)/unlock by a single call, and replace the existing open codes with this helper. The function checks the PCM running state to prevent setting the wrong state, too, for more safety.
