PS3, Line 41: 	temp = pcidev_scandev(&filter, NULL);
            : 	for (; temp; temp = pcidev_scandev(&filter, temp)) {
I guess this could also be written as

while ((temp = pcidev_scandev(&filter, temp))

with `temp` initialized to `NULL`, ofc.

PS3, Line 43: 		if (pci_filter_match(&filter, temp)) {
That's what pcidev_scandev() does, isn't it?
