Dropping the extra mailing lists and Dave, this is a rather trivial thing.

The would have to be "unsigned int" according to the function
signature.

But the most straightforward change is to simply convert to:
dev_priv->bridge_dev = pci_get_domain_bus_and_slot(0, 0,
PCI_DEVFN(0, 0));
Can you please resend like that.
Looks like this is a part of abigger series, so others may prefer
latter form too, to avoid the variable.
