The patch looks good and I appreciate what you're doing, but I question
the usefulness of adding Fixes: tags for trivial stuff like this. I'd
prefer Fixes: was reserved for actual fixes that should be backported to
any kernels that have the commit being fixed.

The same applies to many other patches you've sent recently.
