En caso de que el dispositivo tenga un error de firmware no fatal durante la prueba, el controlador informar\u00e1 el error al usuario a trav\u00e9s de devlink. Esto activar\u00e1 un WARN_ON, ya que mlx5 llama a devlink_register() en \u00faltimo lugar. Para evitar WARN_ON[1], cambie mlx5 para invocar primero a devl_register() bajo el bloqueo devlink.
