Subject[ 058/150] ALSA: hda - hdmi: ELD shouldnt be valid after unplug
Date
3.8-stable review patch.  If anyone has any objections, please let me know.

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

From: David Henningsson <david.henningsson@canonical.com>

commit bbfd8a19b6913f50a362457c34d49bfafe5e456e upstream.

Currently, eld_valid is never set to false, except at kernel module
load time. This patch makes sure that eld is no longer valid when
the cable is (hot-)unplugged.
