Subject: [PATCH 3.13 052/149] ALSA: hda - Use analog beep for Thinkpads with AD1984 codecs

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

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

From: Takashi Iwai <tiwai@...e.de>

commit f3e9b59cb948e2328bc06635ad39572d5b7b4791 upstream.

For making the driver behavior compatible with the earlier kernels,
use the analog beep in the loopback path instead of the digital beep.
