In old IA64 specific pci_domain_nr() It was macro defines: #define PCI_CONTROLLER(busdev) ((struct pci_controller *) busdev->sysdata) #define pci_domain_nr(busdev) (PCI_CONTROLLER(busdev)->segment) Both pci_dev * and pci_bus * have opaque sysdata, so IA64 specific pci_domain_nr() could get the pci_controller and return the exact domain number, but now we use common pci_domain_nr() functions, so we should fix this warning.
