This turns content protection property to be DESIRED and hdcp update_pipe left with property to be in DESIRED state but actual hdcp->value was ENABLED. This issue is caught with DP MST setup, where we have multiple connector in same DP_MST topology. When disabling HDCP on one of DP MST connector leads to set the crtc state need_modeset to true for all other crtc driving the other DP-MST topology connectors. This turns up other DP MST connectors CP property to be DESIRED despite the actual hdcp->value is ENABLED.
