Instead of doing a full modeset to enable/disable content protection, simply go through the update_pipe flow which was introduced in the related patch below. This avoids flashing the screen every time the user starts viewing protected content.

IMHO intel_crtc_check_fastset() make sure that every crtc_state->mode_changed will not turn up to a modeset. It seems it is already being taken care.
Thanks, Anshuman Gupta.
