Merge tag 'char-misc-4.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
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.
