Merge tag 'driver-core-5.13-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 changes for 5.13-rc1.

  Nothing major, just lots of little core changes and cleanups, notable
  things are:

   - finally set 'fw_devlink=on' by default.

     All reported issues with this have been shaken out over the past 9
     months or so, but we will be paying attention to any fallout here
     in case we need to revert this as the default boot value (symptoms
     of problems are a simple lack of booting)

   - fixes found to be needed by fw_devlink=on value in some subsystems
     (like clock).

   - delayed work initialization cleanup

   - driver core cleanups and minor updates

   - software node cleanups and tweaks

   - devtmpfs cleanups

   - minor debugfs cleanups

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