Exponer ivpu_send_receive_internal(), que ahora es utilizado por la entrada D0i3, la inicialización de DCT y las funciones de inicialización de HWS. Estas funciones se han modificado para devolver códigos de error de forma elegante, en lugar de iniciar la recuperación. Las funciones actualizadas se invocan dentro de ivpu_probe() e ivpu_resume(), lo que garantiza que cualquier error encontrado durante estas etapas dé como resultado una secuencia de desmontaje o apagado adecuada. El enfoque anterior de activar la recuperación dentro de estas funciones podría conducir a una condición de ejecución, lo que podría causar un comportamiento indefinido y fallas del kernel debido a desreferencias de puntero nulo.",
