So it does looks like the "data" parameter is not needed at all:
void drm_connector_oob_hotplug_event(struct fwnode_handle *connector_fwnode)
{
struct drm_connector *connector;
connector = drm_connector_find_by_fwnode(connector_fwnode);
if (IS_ERR(connector))
return;
if (connector->funcs->oob_hotplug_event)
connector->funcs->oob_hotplug_event(connector);
drm_connector_put(connector);
}
