[Intel-gfx] [PATCH v3 1/4] drm/i915/hdcp: Use intel_connector argument in intel_hdcp_shim
Suraj Kandpal

Mon Aug 28 06:33:58 UTC 2023
Update intel_hdcp_shim funcs specifically read_2_2_message,
write_2_2_message and config_stream_type to use intel_connector
argument instead of intel_digital_port as this will help in getting
correct aux later for dp mst scenarios also already hdcp funcs
derive digital_port from connector and then many funcs again get back
the connector from dig_port which doesn't seem right.
Connector specific hdcp functions can derive dig_port on need basis.
