[ 009/102] Revert "ALSA: hda - Dont set up active streams twice"

From: Greg Kroah-Hartman
Date: Fri May 17 2013 - 18:27:41 EST


3.9-stable review patch. If anyone has any objections, please let me know.

------------------

From: Takashi Iwai <tiwai@xxxxxxx>

commit 6c35ae3c327ef4b5f51d3428d2ba47ac2153e882 upstream.

This reverts commit affdb62b815b38261f09f9d4ec210a35c7ffb1f3.

The commit introduced a regression with AD codecs where the stream is
always clean up. Since the patch is just a minor optimization and
reverting the commit fixes the issue, let's just revert it.
