Merge tag 'char-misc-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc/IIO/etc driver updates from Greg KH:
"Here is the big set of char, misc, iio, counter, fpga, and other small
driver subsystems for 7.3-rc1.

Overall, due to some driver removals we only added a bit more code
than removed, which was a nice change. Highlights in this merge
request are:

- Loads of IIO driver updates and additions

- binder driver updates (more on that below...)

- Removal of the SGI XP and GRU drivers as they are not used anymore
and turn out to be pretty insecure overall

- Removal of the obsolete ibmasm driver as it's not being used
anymore

- Coresight driver updates and additions

- Mei driver udpates

- Counter driver updates

- FPGA driver updates

- ICC driver updates

- lots and lots of other tiny driver updates to resolve reported
issues

All of these have been in linux-next for a while"
