Always work off of the latest kernel tree.  Ideally linux-next or the
staging.git staging-next tree.  Worse case, Linus's tree.  But never off
of an old kernel tree, that will only cause you to duplicate work that
others have done :(

Please resync against 4.18-rc1 and see why I say this when trying to
apply your patch...

thanks,
