Esta advertencia es causada por work-\u0026gt;func == NULL, lo que significa que falta la inicializaci\u00f3n del trabajo. Esto puede suceder, ya que input_dev-\u0026gt;close() llama a cancel_work_sync(\u0026amp;dev-\u0026gt;work), pero la inicializaci\u00f3n dev-\u0026gt;work ocurre _despu\u00e9s_ de la llamada input_register_device().
