Thanks, Applied to https://gitlab.freedesktop.org/drm/misc/kernel.git (drm-misc-next) [1/4] drm/panel: have drm_panel_add/remove manage a list reference https://gitlab.freedesktop.org/drm/misc/kernel/-/commit/61aebeadff40cded27168e53406e0120ad66e114 [2/4] drm/bridge/panel: hold a reference to the wrapped panel https://gitlab.freedesktop.org/drm/misc/kernel/-/commit/8f79d34ea8950fd825e0d6ecd713705a42f06417 [3/4] drm/panel: of_drm_find_panel() return a counted reference https://gitlab.freedesktop.org/drm/misc/kernel/-/commit/b71a623598d319cae2acd9df1b297cc948c58bc7 [4/4] drm/panel: find_panel_by_fwnode() return a counted reference https://gitlab.freedesktop.org/drm/misc/kernel/-/commit/ac3baea883dab989178dd4186090d6bcf52b8d55 -- Neil
