Subject: [PATCH 3.8 72/91] drm/i915: quirk away phantom LVDS on Intel's D525MW mainboard

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

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

From: Jani Nikula <jani.nikula@...el.com>

commit dcf6d294830d46b0e6901477fb4bf455281d90c8 upstream.

This replaceable mainboard only has a VGA-out, yet it claims to also have
a connected LVDS header.
