Personally, I think you are going to find that this is going to take
more work to get this cleaned up in the staging tree and then out of it
into the "real" part of the kernel, instead of just doing the needed
work out of the tree now and then submitting it "properly" to the right
part of the tree.

But hey, who am I to judge people who like to do extra work!  :)

I'll go queue this up now, good luck!
