Merge tag 'char-misc-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Browse Source 
Pull char/misc updates from Greg KH:
 "Here is the "big" char/misc driver patchset for 4.13-rc1.

  Lots of stuff in here, a large thunderbolt update, w1 driver header
  reorg, the new mux driver subsystem, google firmware driver updates,
  and a raft of other smaller things. Full details in the shortlog.

  All of these have been in linux-next for a while with the only
  reported issue being a merge problem with this tree and the jc-docs
  tree in the w1 documentation area"
