El error del kernel que se muestra a continuación se produjo debido a un flujo de gestión de errores incorrecto cuando falla pci_setup_device(). Se ha añadido pci_iov_scan_device(), que gestiona la asignación y configuración de virtfn y realiza la limpieza si falla pci_setup_device(), de modo que pci_iov_add_virtfn() no necesite llamar a pci_stop_and_remove_bus_device().
