I'm guessing you decided to separate things out to make sure this patch
is purely the result of a coccinelle run w/o manual changes?

It looks like the patch to remove the unused variables is a 'COCCI'
patch too, so maybe it would make sense to run it here directly after
the first coccinelle run, and squash the result into this patch? The
resulting patch would still be entirely auto-generated, and wouldn't
have these somewhat odd unused variables. Thoughts?

Thanks,
