Char/Misc driver fixes for 5.5-rc2

Here are 6 small fixes for some reported char/misc driver issues:
  - fix build warnings with new 'awk' with the raid6 code
  - 4 interconnect driver bugfixes
  - binder fix for reported problem
 
 All of these except the binder fix have been in linux-next with no
 reported issues.  The binder fix is "new" but Todd says it is good as he
 has tested it :)
