Linus Torvalds c01c0716cc Driver core changes for 5.13-rc1 
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.
