Subject: [PATCH 3.8 71/91] drm/i915: quirk away phantom LVDS on Intel's D510MO mainboard

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

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

From: Chris Wilson <chris@...is-wilson.co.uk>

commit e5614f0c2d0f4d7f0b8ef745d34593baf2c5dbf8 upstream.

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