This series collects some minor improvements and fixes previously part of
[0], hence the "v7" version number.

It adds a /sys/kernel/debug/dri/bridges file showing all bridges between
drm_bridge_add() and drm_bridge_remove(), which might not be bound to any
encoder and thus not visible anywhere in debugfs.
