When fixing these kinds of things, please just make it use '%pR' instead.

A simple

	printk(KERN_DEBUG "bus: %02x index %x %pR\n", busnum, j, res);

should do the right thing, printing the resource with nice human-readable 
flags. Including things like 64-bit/prefetching information for memory 
resources etc that the current manual resource printout doesn't do.
