The pci_dev_put() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.

The same patch was posted independently (and earlier) by Maninder Singh,
but I think we concluded that the code was more understandable without
this change, as the test within pci_dev_put() is more of a safety net.
