Commit0848814aa2("drm/i915/dp: Fix connector DSC HW state readout") moved the DSC HW state readout to a connector specific hook, however only added the hook for DP MST connectors, not for DP SST ones. Fix adding the hook for SST connectors as well. This fixes the following warn on platforms where BIOS enables DSC: [ 66.208601] i915 0000:00:02.0: drm_WARN_ON(!connector->dp.dsc_decompression_aux || !connector->dp.dsc_decompression_enabled) ...
