Thanks, I've read the top part of that file. The reason I've declared those
two macroes in pci_ids.h is that I'm using them both in the
main driver (rp1-pci.c) and in drivers/pci/quirks.c.

I suppose I could move DECLARE_PCI_FIXUP_FINAL() inside rp1-pci.c to keep
those two defines local, but judging from the number of entries of
DECLARE_PCI_FIXP_FINAL found in quirks.c versus the occurences found in
respective driver, I assumed the preferred way was to place it in quirks.c.

Many thanks,
Andrea
