As per https://patchwork.freedesktop.org/series/63023/ this issue is caused because device connected at DP port declared itself as a repeater with zero HDCP sinks connected to it. So I915 is reacting as it supposed to be by failing the HDCP authentication.

So not an I915 Bug.

To capture this root cause in the debug log new change is submitted at https://patchwork.freedesktop.org/series/63217/. Will be merged when the review is completed.
