Subject: [PATCH] INTEL DRM DRIVERS : No LVDS hardware on Intel D410PT and
 D425KT

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

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

Signed-off-by: Rob Pearce <rob@...tspace.org.uk>
---
Patch revised to match the D425KT exactly as the D425KTW does have LVDS. 
According to Intel's documentation, the D410PTL and D410PLTW don't.
