From 70372a7566b5e552dbe48abdac08c275081d8558 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 18 Dec 2014 10:02:41 +0100 Subject: ALSA: pcm: Don't leave PREPARED state after draining When a PCM draining is performed to an empty stream that has been already in PREPARED state, the current code just ignores and leaves as it is, although the drain is supposed to set all such streams to SETUP state. This patch covers that overlooked case.
