What checkpatch is saying is about *new* code, not the existing one.

You need to have a *reason* to change the way the existing code works
and the above explanation doesn't sound like a good one to me in this
particular case.

Please don't do any >80 columns cleanups in any patches you want me to apply.
Seriously.  This is irritating and unuseful.

And if you don't want checkpatch to complain about that, please send a patch
to modify checkpatch accordingly.

Thanks!
