of_drm_find_bridge() is deprecated. Move to its replacement of_drm_find_and_get_bridge() which gets a bridge reference, and ensure it is put when done. We need to handle the two cases: when a panel is found and when it isn't, even though the latter is not supported. So: * in case a panel is not found and bridge is, get a reference to the found bridge * in case a panel is found, get a reference to the panel_bridge when it is added, so the following code always get exactly one reference that it needs to put Finally, use the next_bridge pointer in struct drm_bridge in order to simplify putting the reference.
