-    drm: Don't grab an fb reference for the idr
-
-we've switched to weak references, broke that assumption but forgot to
-fix it up.
-
-Since we still force-disable planes it's only possible to hit this
-when racing multiple rmfb with fbdev restoring or similar evil things.
-As long as userspace is nice it's impossible to hit the BUG_ON.
-
-But the BUG_ON would most likely be hit from fbdev code, which usually
-invovles the console_lock besides all modeset locks. So very likely
-we'd never get the bug reports if this was hit in the wild, hence
-better be safe than sorry and backport.

-Spotted by Matt Roper while reviewing other patches.
