Subject: [PATCH 3.14 05/87] ALSA: hda - initialize audio InfoFrame to be all zero

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

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

From: Mengdong Lin <mengdong.lin@...el.com>

commit caaf5ef9493f72390905f1e97b310b8906d32dac upstream.

This patch initialized the local audio InfoFrame variable 'ai' to be all zero,
thus the data bytes will indicate "Refer to Stream Header" by default.
