Lance, you didn't add all the "prefix" stuff in AER, but since you're
touching it, I think things will make more sense if you clean it up at
the same time.  There are a lot of printk() calls there that should be
converted to dev_printk().

I think I see why it was done that way -- it sticks either
KERN_WARNING or KERN_ERR at the beginning of the prefix, then uses
plain printk() later.  I guess that means you only have to pass around
the prefix argument, rather than both a "level" and a "struct pci_dev
*".  But I think it will be simpler overall to pass both and take
advantage of dev_printk() and stop emulating it.
