This is not a trivial patch, it changes the behavior of the code and is
buggy.
Please read the documentationfor pci_get_device() on how to use it
properly. It can not be used in pci_find_slot() as the reference
counting will be all wrong. You need to just work to get rid of
pci_find_slot() and then remove the whole function to get rid of the
warning :)

What about the modules that want to use these functions? Are they all
now gone? If so, just drop the whole function.
