FYI: if you want to add HDCP support, then please contact me. I have code
available for that (i.e. the public API part), although it is out of date.

But if you want to enable HDCP in this driver, then I would be very happy
to clean it up and post patches for that. It is something we (i.e. Cisco)
have been using for several years now in out-of-tree drivers.

I will try to review this patch in the next few days.
