        /* Create a device template */
-       memset(&dev0, 0, sizeof(dev0));
-       dev0.bus = bus;
+       dev0 = kmalloc(sizeof(struct pci_dev), GFP_ATOMIC);
+       if (dev0 == NULL)
+               BUG();
+       memset(dev0, 0, sizeof(dev0));
+       dev0->bus = bus;

Why is this atomic? I think we do not scan from interrupts, only from init/swapper and insmod contexts.
