From: Thierry Reding <treding-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>
The number of the head specifies the index of the display controller
unit and is required to properly configure outputs so that they receive
video data from the correct source.

Hi Olof, Kevin,
Stephen requested that I send this patch your way so that it can be
applied for 3.14. They aren't strictly necessary because there's a
fallback if they are missing but if they aren't present, the driver
will output undesirable error messages.
Thanks,
Thierry
