Right. The changelog is extremely confusing as is the ordering in the
patch series. You usually write something like "in preparation for
enabling XYZ support, add helper functions" and include the
conversions immediately after the helpers.
I'll fix the issues myself later today when I have the change to merge
patches. That is, unless you beat me to it and send a v2 of the
series.
