Thanks for the quick reply.

There is another pdev patch that I just sent out. [1] It has to go into 
the intel tree. After it landed, I want to get this patchset into 
drm-misc-next ASAP. Otherwise, drm-tip would stop building.

This should fix things in the correct order and finally remove pdev for 
current drivers.

Best regards
Thomas
