It seems that you are creating dummy_dev as an alternative to passing
just the PCI bus/device/function. Wouldn't be easier to just use BDF
instead. Dummy arguments on the stack can lead to more corner cases
in the future if device subsystem changes.

Must be marked experimental (or internal).
The pci_device should be marked const.

ditto
