Pull char/misc driver fixes from Greg KH:
 "Here are some small char and misc driver fixes for 5.11-rc3.

  The majority here are fixes for the habanalabs drivers, but also in
  here are:

   - crypto driver fix

   - pvpanic driver fix

   - updated font file

   - interconnect driver fixes

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