Driver core changes for 6.9-rc1

Here is the "big" set of driver core and kernfs changes for 6.9-rc1.

Nothing all that crazy here, just some good updates that include:
  - automatic attribute group hiding from Dan Williams (he fixed up my
    horrible attempt at doing this.)
  - kobject lock contention fixes from Eric Dumazet
  - driver core cleanups from Andy
  - kernfs rcu work from Tejun
  - fw_devlink changes to resolve some reported issues
  - other minor changes, all details in the shortlog

All of these have been in linux-next for a long time with no reported
issues.
