#     
#     Pull char/misc fixes from Greg KH:
#      "Here are some small driver fixes for 6.4-rc4. They are just two
#       different types:
#     
#        - binder fixes and reverts for reported problems and regressions in
#          the binder "driver".
#     
#        - coresight driver fixes for reported problems.
#     
#       All of these have been in linux-next for over a week with no reported
#       problems"
#
