Char/misc driver fixes for 5.13-rc3 

Here is a big set of char/misc/other driver fixes for 5.13-rc3.
 
 The majority here is the fallout of the umn.edu re-review of all prior
 submissions.  That resulted in a bunch of reverts along with the
 "correct" changes made, such that there is no regression of any of the
 potential fixes that were made by those individuals.  I would like to
 thank the over 80 different developers who helped with the review and
 fixes for this mess.
 
 Other than that, there's a few habanna driver fixes for reported issues,
 and some dyndbg fixes for reported problems.
 
 All of these have been in linux-next for a while with no reported
 problems.
