Pull char/misc driver updates from Greg KH:
"Here is the big char/misc driver update for 4.4-rc1. Lots of
different driver and subsystem updates, hwtracing being the largest
with the addition of some new platforms that are now supported. Full
details in the shortlog.
All of these have been in linux-next for a long time with no reported
issues"
