Staging/IIO fixes for 5.1-rc6 

Here is a bunch of IIO driver fixes, and some smaller staging driver
 fixes, for 5.1-rc6.  The IIO fixes were delayed due to my vacation, but
 all resolve a number of reported issues and have been in linux-next for
 a few weeks with no reported issues.
 
 The other staging driver fixes are all tiny, resolving some reported
 issues in the comedi and most drivers, as well as some erofs fixes.
 
 All of these patches have been in linux-next with no reported issues.
