I guess we could live with that. pci_find_device() or its successor, the
hisax_find_pci_device() hack, is only called during device setup, once
for most drivers and at the very most 24 times for hfc_pci. Someone
would have to rmmod/insmod a HiSax module more than a hundred million
times to accumulate four billion calls.
