[PATCH v3 22/22] drm/todo: add entry to remove devm_drm_put_bridge()

[Luca Ceresoli <luca.ceresoli@bootlin.com>]

devm_drm_put_bridge() is a temporary workaround waiting for the panel
bridge lifetime rework. Add a TODO entry to not forget it must be removed
after such rework.

+Remove devm_drm_put_bridge()
+----------------------------
+
+Due to how the panel bridge handles the drm_bridge object lifetime, special
+care must be taken to dispose of the drm_bridge object when the
+panel_bridge is removed. This is currently managed using
+devm_drm_put_bridge(), but that is an unsafe, temporary workaround. To fix
+that, the DRM panel lifetime needs to be reworked. After the rework is
+done, remove devm_drm_put_bridge() and the TODO in
+drm_panel_bridge_remove().
