From my POV having the Cc stable in there is fine if Michael actually
wants them to go there. GregKH will vacuum them up once they hit Linus'
tree and we don't need to think about it anymore.

Alternatively, Michael could put the patch in a separate branch and we
could both merge that.

Or even, seeing how its a single patch and git mostly does the right
thing, we could just merge it independently in both trees and let git
sort it out at merge time.
