Subject: [PATCH 0/3] Simplify panel bridge cleanup

The goal of this series is to simplify driver code when they need to clean up
a previously allocated panel bridge.
Few drivers have "is_panel_bridge" flag to be able to distinguish a
drm_panel_bridge from "simple" drm_bridge.
To remove this flag I propose to
- let drm_panel_bridge_remove() check if the bridge provided in parameter is
  really a drm_panel_bridge.
- add drm_of_panel_bridge_remove() to remove a bridge given DT port and
  endpoint
Finally that allow to remove drm_bridge structure and "is_panel_bridge" flag
from stm driver internal structure.

Benjamin Gaignard (3):
  drm/bridge: make drm_panel_bridge_remove more robust
  drm/drm_of: add drm_of_panel_bridge_remove function
  drm/stm: ltdc: remove bridge from driver internal structure
