I don't see much value in this replacement and checkpatch complaining
about the existing code base is not something to worry about in
general.

I do agree that in general checkpatch should not really be used as
the sole argument in favor of changing existing code.
So removing the "resolve following checkpatch issue" from the
commit message and replacing it with something like "to improve
readability" would be better.
