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

From: Rob Pearce <[email protected]>

These Intel D410PT 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. Tested against 3.9.10 and 3.11.4

At least this one here has a KTW variant with lvds connector. I think we
need a DMI_EXACT_MATCH. I haven't found out whether the D410PT board also
has such a cousin, so please digg in a bit for me.

Thanks, Daniel

Yes, you're right, sorry. I've had a dig and it looks like the D410PT
variants don't have LVDS (the differences in that range are legacy I/O,
PCIe and wireless). I'll re-submit with the 425 as an exact match.

Rob
