[alsa-devel] [PATCH] ALSA: hda - initialize audio InfoFrame to be all zero

[mengdong.lin at intel.com]

From: Mengdong Lin <mengdong.lin at intel.com>

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.
