Merge tag 'driver-core-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core update from Greg KH:
 "Here is the "big" driver core update for 4.14-rc1.

  It's really not all that big, the largest thing here being some
  firmware tests to help ensure that that crazy api is working properly.

  There's also a new uevent for when a driver is bound or unbound from a
  device, fixing a hole in the driver model that's been there since the
  very beginning. Many thanks to Dmitry for being persistent and
  pointing out how wrong I was about this all along :)

  Patches for the new uevents are already in the systemd tree, if people
  want to play around with them.

  Otherwise just a number of other small api changes and updates here,
  nothing major. All of these patches have been in linux-next for a
  while with no reported issues"

* tag 'driver-core-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (28 commits)
  driver core: bus: Fix a potential double free
  Do not disable driver and bus shutdown hook when class shutdown hook is set.
  base: topology: constify attribute_group structures.
  base: Convert to using %pOF instead of full_name
  kernfs: Clarify lockdep name for kn->count
  fbdev: uvesafb: remove DRIVER_ATTR() usage
