This code is over a decade old (13 years old to be precise) and there was
something odd between Bjorn's and Jesse's patches, as per:

  89a74ecccd1f ("PCI: add pci_bus_for_each_resource(), remove direct 
bus->resource[] refs")
  cf26e8dc4194 ("pcmcia: do not autoadd root PCI bus resources")

I wouldn't, personally.  The change you are proposing is self-explanatory
and somewhat in-line with what is there already - unless I am also reading
the current implementation wrong.

That said, Dominik is the maintainer of PCMCIA driver, so his is the last
word, so to speak. :)

No need, really.  Again, unless Dominik thinks otherwise.
