Merge tag 'driver-core-6.0-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core fixes from Greg KH:
 "Here are some small driver core fixes for some oft-reported problems
  in 6.0-rc1.  They include:

   - a bunch of reverts to handle driver_deferred_probe_check_state()
     problems that were part of the 6.0-rc1 merge.

   - firmware_loader bugfixes now that the code is being properly tested
     and used by others

   - arch_topology fix

   - deferred driver probe bugfix to solve a long-suffering amba bus
     problem that many people have reported.

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