pci_get_bus_and_slot() is restrictive such that it assumes domain=0 as where a PCI device is present. This restricts the device drivers to be reused for other domain numbers. Getting ready to remove pci_get_bus_and_slot() function in favor of pci_get_domain_bus_and_slot(). struct riva_par has a pointer to struct pci_dev. Use the pci_dev member to extract the domain information. Change the function signature for CalcStateExt and RivaGetConfig to pass in struct pci_dev in addition to RIVA_HW_INST so that code inside the riva_hw.c can also calculate domain number and pass it to pci_get_domain_bus_and_slot().
