Does it really take 4 reviewers for a single line change?
I'd rather have each of these reviewers submit patches to
different files rather than have them review this pretty
trivial change to a pretty old driver that really doesn't
need much in the way of changes.
And please, if you modify this file all, please be more
comprehensive in the printk conversions.
There are many printks in this file, not just this one.
