El controlador maestro I3C puede recibir una IBI de un dispositivo de destino que a\u00fan no se ha sondeado. En tales casos, el maestro llama a `i3c_master_queue_ibi()` para poner en cola una tarea de trabajo IBI, lo que genera el error \"No se puede manejar la lectura del kernel desde memoria ilegible\" y provoca un p\u00e1nico del kernel. Flujo t\u00edpico de manejo de IBI: 1. El maestro I3C escanea los dispositivos de destino y sondea sus respectivos controladores. 2. El controlador del dispositivo de destino llama a `i3c_device_request_ibi()` para habilitar IBI y asigna `dev->ibi = ibi`. 3. El maestro I3C recibe una IBI del dispositivo de destino y llama a `i3c_master_queue_ibi()` para poner en cola la tarea de manejo de IBI del controlador del dispositivo de destino. Sin embargo, dado que los eventos del dispositivo de destino son as\u00edncronos a la secuencia de sondeo I3C, el paso 3 puede ocurrir antes del paso 2, lo que provoca que `dev->ibi` sea `NULL` y provoque un p\u00e1nico del kernel.
