De acuerdo con el seguimiento de llamadas a continuaci\u00f3n: cmdq_mbox_shutdown mbox_free_channel mbox_controller_unregister __devm_mbox_controller_unregister ...

El controlador CMDQ usa devm_mbox_controller_register() en cmdq_probe() para vincular el cmdq al mbox_controller, por lo que devm_mbox_controller_unregister() cancelar\u00e1 autom\u00e1ticamente el registro del dispositivo vinculado al controlador del buz\u00f3n cuando se elimine el recurso administrado por el dispositivo.
