-	for (nodeid = 0; !res && (nodeid < CONFIG_MAX_PHYSICAL_CPUS);
nodeid++) {
-		struct device *dev;
-		dev = __f0_dev[nodeid];
-		if (!dev)
-			continue;
+	while (!res
+	       && (dev = dev_find_pci_device(PCI_VENDOR_ID_AMD, 0x1100,
dev))) {
 		for (link = 0; !res && (link < 3); link++) {
 			res = probe_resource(dev, 0x100 + (reg | link));
 		}
+		nodeid++;
 	}

Thanks for the quick review.  The reason I didn't keep it is because
dev_find_pci_device is updating dev, which is where the search starts from
each time.  You shouldn't find the same device twice using that function, or
you have a loop in the device list.

I can put it back in, or a comment explaining it if you want, though.

Thanks,
Myles
