Ok, reviewed all the refcounting prep work. Just minor stuff, so I guess
you'll pull them into drm-next directly after polishing?

I have a bunch of pull requests I'll send out today, so could do a
drm-next day.

For the actual drm_connector refcounting I'd like to soak the prep patches
a bit first, and I also need to think a bit more about those ;-)

Cheers, Daniel
