Pull char/misc driver fixes from Greg KH:
 "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"
