I added a couple of DRM_ERROR... lines to see if I passed if(drm_rgb_quant_range_selectable and I don't.
But even if I did I don't think that patch will work as I only get one message at the start - I would have expected that flipping between tvrgb and bypass (which works OK) would have generated more, but it doesn't.
Changing the AVI infoframe requires a full modeset, changing the output_csc does not. The AVI infoframe change only takes affect when you force a full modeset (e.g., switch modes with xrandr). It's trivial to change the code to force a full modeset rather than just updating the output_csc state when you update the property, but I left them decoupled now for testing.
