3.13.11-ckt18 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Takashi Iwai <[email protected]> commit 70372a7566b5e552dbe48abdac08c275081d8558 upstream. 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.
