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

Pull driver core updates from Greg KH:
 "Here is the big driver core update for 4.13-rc1.

  The large majority of this is a lot of cleanup of old fields in the
  driver core structures and their remaining usages in random drivers.
  All of those fixes have been reviewed by the various subsystem
  maintainers. There's also some small firmware updates in here, a new
  kobject uevent api interface that makes userspace interaction easier,
  and a few other minor things.

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