Thanks Stephen,

I'll call these out (I think we have 3 of them now) when I send Greg a pull request as
probably best place to tidy this up is when merging into char-misc which has
merged rc2 with Al's patch.

Greg, let me know if you'd rather I handled these in the iio tree
(probably a merge of rc2 as I'd rather not rebase)
