Merge tag 'driver-core-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core updates from Greg KH:
 "Here is the driver core / firmware changes for 4.2-rc1.

  A number of small changes all over the place in the driver core, and
  in the firmware subsystem.  Nothing really major, full details in the
  shortlog.  Some of it is a bit of churn, given that the platform
  driver probing changes was found to not work well, so they were
  reverted.

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