OK, now reviewed.

The change looks mostly OK, but a couple of things:

- hp_pin is not guaranteed to be present;
  it should check the case of hp_pin=0, too

- Please give some comment to the function, otherwise it's really
  mystery without answer.
  You can just put the text in the patch description there.


Could you fix these and resubmit?  Thanks!
