Merge tag 'driver-core-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core updates from Greg KH:
 "Here is the big set of driver core patches for 5.15-rc1.

  These do change a number of different things across different
  subsystems, and because of that, there were 2 stable tags created that
  might have already come into your tree from different pulls that did
  the following

   - changed the bus remove callback to return void

   - sysfs iomem_get_mapping rework

  Other than those two things, there's only a few small things in here:

   - kernfs performance improvements for huge numbers of sysfs users at
     once

   - tiny api cleanups

   - other minor changes

  All of these have been in linux-next for a while with no reported
  problems, other than the before-mentioned merge issue"
