I think I am the one who should take it. I will apply it when v4.14-rc1
will be released as it is too late for me for 4.14 now.

However I am not against the fact that it is applied through an other
tree because we don't touch this file for the next release so there is
no risk for a conflict, I can give my Acked-by if needed.
