The series looks good, but it needs to be rebased due to this change: http://www.spinics.net/lists/linux-media/msg101733.html Regarding patch 3/11: as you may know we're moving from DocBook to sphinx for the documentation in 4.8. The git branch with that code is here: https://git.linuxtv.org/media_tree.git/log/?h=docs-next If you can redo this patch 3/11 on top of that branch, then that would be great.
