Subject: [PATCH 3.8 73/91] drm/i915: No LVDS hardware on Intel D410PT and D425KT

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

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

From: Rob Pearce <rob@...tspace.org.uk>

commit 645378d85ee524e429aa4cf52806047b56cdc596 upstream.

The Intel D410PT(LW) and D425KT Mini-ITX desktop boards both show up as
having LVDS but the hardware is not populated. This patch adds them to
the list of such systems. Patch is against 3.11.4

v2: Patch revised to match the D425KT exactly as the D425KTW does have
LVDS.  According to Intel's documentation, the D410PTL and D410PLTW
don't.
