Actually, WARN(1, foo) is by far the most common use of WARN.
More than half of all uses.

Code is decidedly not music.

This stuff is mostly craft not art and consistency in
craft has value.

You might also note I didn't call it a fix, I called it
a whitespace cleanup.

And again, I don't much care if it's applied to
arch/alpha or not.  I haven't had an alpha since I gave
away my AlphaStation a decade ago.
