Char/Misc driver patches for 4.3-rc1

Here's the "big" char/misc driver update for 4.3-rc1.
 
 Not much really interesting here, just a number of little changes all
 over the place, and some nice consolidation of the nvmem drivers to a
 common framework.  As usual, the mei drivers stand out as the largest
 "churn" to handle new devices and features in their hardware.
 
 All have been in linux-next for a while with no issues.
