Merge tag 'char-misc-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc driver patches from Greg KH:
"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"
