Pull driver core changes from Greg KH:
 "Here is the small set of driver core and debugfs updates for 5.14-rc1.

  Included in here are:

   - debugfs api cleanups (touched some drivers)

   - devres updates

   - tiny driver core updates and tweaks

  Nothing major in here at all, and all have been in linux-next for a
  while with no reported issues"
