Staging/IIO fixes for 4.14-rc4

Browse Source 
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.
 
 All have been linux-next for a few weeks with no reported issues.
