I don't see this in linux-next yet so following up to see if anything else is
needed to get this merged.

Hi Jeff,

The arm tree uses a separate submission system for reviewed
patches to get into the tree, see

https://www.arm.linux.org.uk/developer/patches/info.php
https://www.arm.linux.org.uk/developer/patches/section.php?section=0

I looked at this file as well during build testing
and ended up combining the change with a cleanup,
If you like, I can send my version instead, see below.

Thanks for the pointer. Hard to keep track of these when submitting tree-wide!

Please send your version since it has additional cleanup.
