If you want to make an hdcp interface naming agnostic to the
implementation details, why do we have to have "fw" in the naming, at
all?

Why is "cp" duplicated?

You're calling the file "i915 Content Protection Firmware High-bandwidth
Digital Content Protection Interface".

Why are the names *impossible* to pronounce?

I'd just make this "i915_hdcp_interface".
