PS6, Line 563: 
             : 	/* Add dummy slot to preserve resources, must happen after bus scan */
             : 	struct device *dummy;
             : 	struct device_path dummy_path = { .type = DEVICE_PATH_NONE };
             : 	dummy = alloc_dev(dev->link_list, &dummy_path);
             : 	dummy->ops = &pciexp_hotplug_dummy_ops;
             : 
This causes an error: `[ERROR]  NONE missing set_resources`

I have no idea if `set_resources` is really required for the dummy device, or if it's enough to introduce `DEVICE_PATH_DUMMY` which doesn't print an error during resource allocation.

@Nico, ideas?
