From: Ville Syrjälä <ville.syrj...@linux.intel.com> Make life easier for drivers by filtering out unwanted YCbCr 4:2:0 only modes prior to calling the connector->mode_valid() hook. Currently drivers will still see YCbCr 4:2:0 only modes in said hook, which will likely come as a suprise when the driver has declared no support for such modes (via setting connector->ycbcr_420_allowed to false).
