Merge tag 'driver-core-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull driver core updates from Greg KH:
 "Here is the set of driver core / debugfs patches for 4.15-rc1.

  Not many here, mostly all are debugfs fixes to resolve some
  long-reported problems with files going away with references to them
  in userspace. There's also some SPDX cleanups for the debugfs code, as
  well as a few other minor driver core changes for issues reported by
  people.

  All of these have been in linux-next for a week or more with no
  reported issues"
