Definitely keep it as a separate patch, but I don't think you should
define DEBUG by default; just let people turn it on if desired, and
leave it out otherwise.  There's only a single KERN_DEBUG printk in this
driver, and it seems fine to just convert to pr_debug so it gets left
out of normal builds.
