Driver core patches for 4.21-rc1

Browse source 
Here is the "big" set of driver core patches for 4.21-rc1.
 
 It's not really big, just a number of small changes for some reported
 issues, some documentation updates to hopefully make it harder for
 people to abuse the driver model, and some other minor cleanups.
 
 All of these have been in linux-next for a while with no reported
 issues.
