that prototype return int is required by pci_walk_bus().

drivers/pci/bus.c:void pci_walk_bus(struct pci_bus *top, int
(*cb)(struct pci_dev *, void *)

return 1, will return early from pci_walk_bus().

count_unassigned_resources() is not good name too, as we bail out early.
find_unassigned_resources() is more weird, looks like it want to return resource
