[PATCH 00/24] device link, bridge supplier <-> drm device

Hi!

It was noted by Russel King [1] that bridges (not using components)
might disappear unexpectedly if the owner of the bridge was unbound.
Jyri Sarha had previously noted the same thing with panels [2]. Jyri
came up with using device links to resolve the panel issue, which
was also my (independent) reaction to the note from Russel.

This series builds up to the addition of that link in the last
patch, but in my opinion the other 23 patches do have merit on their
own.

The last patch needs testing, while the others look trivial. That
said, I might have missed some subtlety.

Cheers,
Peter
