The define for_each_pci_dev(d) is: while ((d = pci_get_device(PCI_ANY_ID, PCI_ANY_ID, d)) != NULL) Thus, the list iterator 'd' is always non-NULL so it doesn't need to be checked. So just remove the unnecessary NULL check. Also remove the unnecessary initializer because the list iterator is always initialized.
