Just ignore checkpatch in this case because it's not a warning that your
patch introduced.

Say if you re-name a function, then you *must* re-indent the parameters
because that's a warning the change introduces.  If there is a
checkpatch warning and it's on a line that you touch then you can change
that.  But once you start changing other nearby lines you might run into
trouble.

The other thing that you fixed is you removed unnecessary parentheses
and that's good but it actually broke my review script for renaming
variables.  (Attached).  I do `cat email.txt | rename_rev.pl -a`  It's
easier in mutt.
