-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().
