drm/i915: Eliminate the intel_dp dependency from DRRS
The DRRS code has no use for the intel_dp, replace it with just a crtc pointer. This is just an intermediate step towards making DRRS truly per-crtc. Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220311172428.14685-12-ville.syrjala@linux.intel.com Reviewed-by: Jani Nikula <jani.nikula@intel.com>
