+Subject: [PATCH 2/2] pcm: Don't store the state for SND_PCM_STATE_SUSPENDED
+
+The resume function don't update the dmix->state, if store SUSPENDED
+state in snd_pcm_dmix_state, the write function after resume will
+return error -ESTRPIPE, because the snd_pcm_write_areas() will check
+the state of the pcm device.
+This patch remove the store SND_PCM_STATE_SUSPENDED state operation
+for dmix,dshare,dsnoop.
