    On which platform? There's a lot of them on the architectures that do not
    have PCI at all - same situation as with firewire. Note that you won't
    get any low-level drivers on PCI-less config even on i386, so while I
    agree that more accurate dependency would be nice here (as well as for
    drivers/ieee1394), for all practical purposes the same dependency works
    here.

    BTW, this is more general question - do we expect pci helpers to be present
    on all platforms and do we consider their use acceptable in code that does
    not depend on PCI?

    Again, for infiniband and ieee1394 it's an academical question, since neither
    actually has any hardware it could talk to in .config without CONFIG_PCI...
