This series 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.
It also cleans up the DRM bridge debugfs code by moving code to
drm_bridge.c.

Changes in v8:
- moved more code to drm_bridge.c, which makes adding '#if CONFIG_DEBUG_FS' unnecessary
- a small fix to a harmless bug
- Link to v7: https://lore.kernel.org/r/20250225-drm-debugfs-show-all-bridges-v7-0-8826037ada37@bootlin.com
