This warning is caused by\nwork->func == NULL, which means missing work initialization.\n\nThis may happen, since input_dev->close() calls\ncancel_work_sync(&dev->work), but dev->work initalization happens _after_\ninput_register_device() call.\n\nSo this patch moves dev->work initialization before registering input\ndevice"

Esta advertencia es causada por work->func == NULL, lo que significa que falta la inicializaci\u00f3n del trabajo. Esto puede suceder, ya que input_dev->close() llama a cancel_work_sync(&dev->work), pero la inicializaci\u00f3n dev->work ocurre _despu\u00e9s_ de la llamada input_register_device(). Entonces este parche mueve la inicializaci\u00f3n dev->work antes de registrar el dispositivo de entrada"
