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

From: Greg Kroah-Hartman
Date: Thu Mar 20 2014 - 21:14:26 EST


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

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

From: Takashi Iwai <tiwai@xxxxxxx>

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.
