ASoC: dpcm: fix the BE state on hw_free
While performing hw_free, DPCM checks the BE state but leaves out the suspend state. The suspend state needs to be checked as well, as we might be suspended and then usermode closes rather than resuming the audio stream. This was found by a stress testing of system with playback in loop and killed after few seconds running in background and second script running suspend-resume test in loop Signed-off-by: Vinod Koul <vinod.koul@intel.com> Acked-by: Liam Girdwood <liam.r.girdwood@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org> Cc: stable@vger.kernel.org
