Heh, yeah! The original patch was moving it:

https://git.linuxtv.org/mchehab/experimental.git/commit/?h=all_with_indexes&id=e02d3ba65eba1676b01c82988b8054b88e6e5cdc

It seems I forgot to fix the comment here.

I opted to do just the conversion and place the move patch on a separate
series (yet to be submitted), in order to avoid merge conflicts.
