Having both modes can be beneficial for video playback cases. If you can match the video framerate exactly, and the audio and video clocks come from the same source, you should be able to avoid dropped/repeated frames without expensive operations such as resampling the audio to match video output rate. Rather than add both variants based on the CEA extension short video descriptors in do_cea_modes(), add only one variant there. Once all the EDID has been fully probed, do a loop over the entire probed mode list, during which we add the other variants for all modes that match CEA modes. This allows us to match modes that didn't come via the CEA short video descriptors. For example one Samsung TV here doesn't have the 640x480-60 mode as a SVD, but instead it's specified via a detailed timing descriptor.
