Merge tag 'driver-core-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core updates from Greg KH:
 "Here is the set of changes for the driver core for 5.17-rc1.

  Lots of little things here, including:

   - kobj_type cleanups

   - auxiliary_bus documentation updates

   - auxiliary_device conversions for some drivers (relevant subsystems
     all have provided acks for these)

   - kernfs lock contention reduction for some workloads

   - other tiny cleanups and changes.

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