Staging fixes for 4.7-rc4

Browse Source 
Here are a number of IIO and Staging bugfixes for 4.7-rc4.
 
 Nothing huge, the normal amount of iio driver fixes, and some small
 staging driver bugfixes for some reported problems (2 are reverts of
 patches that went into 4.7-rc1).  All have been in linux-next with no
 reported issues.
