Looking at your various commits in this vein, it really looks like there 
needs to be a function that returns the PCI device, given the struct 
pci_driver pointer.  pci_find_driver() perhaps?

Hm, only about 3 places really use that, and they would want something
that would iterate over all pci devices that were bound to that driver.
As the three places are in OSS drivers, I don't know if it's really
worth adding a pci core function for them :)

thanks,
