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.
version 2: - does the same for vc4 and dw-mipi-dsi
