Anyhow, I see they are still in Andrew's nonmm-unstable tree, so assuming he won't mind me picking them up through IIO instead / as well. If nothing else git will sort this out when the two trees reach linux-next or upstream anyway. +Cc Andrew Morton. this and next two patches applied to the togreg branch of iio.git. I'll push that out as testing for 0-day to do it's sanity checks then it'll go out as iio.git / togreg and get picked up by linux-next.
