Pull char/misc driver updates from Greg KH:
"Here is the big char/misc driver patchset for 4.11-rc1.
Lots of different driver subsystems updated here: rework for the
hyperv subsystem to handle new platforms better, mei and w1 and extcon
driver updates, as well as a number of other "minor" driver updates.
All of these have been in linux-next for a while with no reported
issues"
