[PATCH] checkpatch: Recognise "Debugged-by" tags

[Michael Ellerman]

Currently checkpatch complains about "Debugged-by:" tags:

  WARNING: Non-standard signature: Debugged-by:
  #33:
  Debugged-by: Jane Doe <jane@xxxxxxx>

There are over 150 Debugged-by tags already in the history, so
checkpatch should allow them.

Additionally checkpatch will now catch small typos, eg:

  WARNING: Non-standard signature: 'Debuged-by:' - perhaps 'Debugged-by:'?
  #17:
    Debuged-by: Jane Doe <jane@xxxxxxx>
