Subject: 3.19-rc0: video stops working after update

Hi!

After updating tree based on -pali to
2756d373a3f45a3a9ebf4ac389f9e0e02bd35a93 (and trimming down dts to
make it boot, as I'm still hiting dts size limit), video stops
working.

I also found this nastiness in dmesg:

Ideas welcome.

Best regards,
								Pavel
