Merge tag 'char-misc-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc driver updates from Greg KH:
"Here's the "big" char and misc driver update for 4.9-rc1.
Lots of little things here, all over the driver tree for subsystems
that flow through me. Nothing major that I can discern, full details
are in the shortlog.
All have been in the linux-next tree with no reported issues"
