Deferring the change until i picked it up from Linus or net-next in my 
tree is fine. This driver is not heavily worked on (its actually marked 
as orphaned) so the patch should still apply in a few days.

I will keep it in my patchwork queue of patches to be applied. No extra 
work needed from your side.
