Yeah, I figured I would get this feedback when I chose INFO :-). So in my
defense, HDCP is enabled/disabled quite infrequently and very likely never
in most distros. Further, it's really nice to know whether something went
sideways while HDCP was enabled, or perhaps corresponding to enable/disable.
All said, if this is distruptive upstream, we can carry a s/DEBUG_KMS/INFO/
patch downstream.
