Merge tag 'char-misc-4.15-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc updates from Greg KH:
 "Here is the big set of char/misc and other driver subsystem patches
  for 4.15-rc1.

  There are small changes all over here, hyperv driver updates, pcmcia
  driver updates, w1 driver updats, vme driver updates, nvmem driver
  updates, and lots of other little one-off driver updates as well. The
  shortlog has the full details.

  All of these have been in linux-next for quite a while with no
  reported issues"
