I'm generally skeptical to the kind of "cleanups" that you seem to be
referring to. More often then not they reduce legibility instead of the
opposite.
If checkpatch considered that line to be a problem, I would consider
checkpatch to be utterly broken. That line is perfectly legible, and
padding in a bunch of spaces would make it LESS so, especially since it
would have to be split between lines.
