Pull staging/IIO fixes from Greg KH: "Here are some small staging/IIO driver fixes for 4.14-rc4 Most of these have been in my tree for a while due to travels, sorry for the delay. They resolve a number of small issues reported by people, mostly for the iio drivers. Nothing major in here, full details are in the shortlog.
