This needs two different patches.
In general, if you describe two things that don't relate each other in
your patch, then this is asking for two patches.
On top of that, if you split patches in logical pieces, you usually
make it easier for the reviewers to spot problems.
BTW, please include in your description that this rename is possible
because we didn't release any kernel version with these changes yet,
that's why this is still possible.
