Hello!

Maybe I may go like this:

I know my PCI from the device bus, so:

unsigned long bus_address;
struct pci_bus *my_bus = universe_pci_dev->bus;
bus_address = pci_phys_to_bus(physical_address, my_bus->number);

Since pci_phys_to_bus() is an exported symbol, this should work in my
module, shouldn't it?

Thanks in advance,
Oliver Korpilla
