Some points that I did not pick up on the first time:
1. You have changed the semantics by putting NULL as the last argument of
pci_get_device. The last argument of pci_find_device is the one from
which to start searching for the result. With NULL as the last argument,
it starts the search from the beginning of the list.
2. By immediately dropping the reference count, you have at best preserved
the behavior of pci_find_device, in which the object is not protected from
being freed, and at worst caused the object to be freed immediately, if no
one else has increased its reference count.
