staging and iio driver fixes for 4.15-rc3

Browse Source 
Here are a number of small staging and iio driver fixes for reported
 issues for 4.15-rc3.  Nothing major here, the majority is IIO issues,
 like normal, but there are also some small bugfixes for a few staging
 drivers as well.
 
 Full details are in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 issues.
