[Intel-gfx] [PATCH 0/2] Fix HDCP2 capability check

[Suraj Kandpal]

In DP MST scenarios we derive the connector and in turn the
aux from intel_digital_port which always gave the primary
monitors aux, this caused the capability of the primary
monitor to be checked twice rather than enumerating the
different HDCP capabilities for each monitor because of this
we saw the below issues
-primary monitor = HDCP 1.4 secondary monitor : HDCP 2.2 1.4
i915_display_info reads as : HDCP 1.4 for both monitor

-primary monitor = HDCP 2.2 1.4 secondary monitor : HDCP 1.4
i915_display_info reads as : HDCP 2.2 1.4 for both monitor

Solution is to derive the aux from intel_connector instead.

Suraj Kandpal (2):
  drm/i915/hdcp: Use intel_connector as argument for hdcp_2_2_capable
  drm/i915/hdcp: Use correct aux for capability check scenario
