[PATCH 3.11 047/144] ALSA: hda - Add missing loopback merge path for AD1884/1984 codecs

[Luis Henriques]

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

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

From: Takashi Iwai <tiwai at suse.de>

commit c5eda4c1bf6214332c46fb2f4e7c42a85e5e5643 upstream.

The mixer widget (NID 0x20) of AD1884 and AD1984 codecs isn't
connected directly to the actual I/O paths but only via another mixer
widget (NID 0x21).  We need a similar fix as we did for AD1882.
