Ville Syrjälä 541ab84d2b drm/i915: Allow DBLSCAN user modes with eDP/LVDS/DSI ... When encountering a connector with the scaling mode property both intel and modesetting ddxs sometimes add tons of DBLSCAN modes to the output's mode list. The idea presumably being that since the output will be going through the panel fitter anyway we can pretend to use any kind of mode. Sadly that means we can't reject user modes with the DBLSCAN flag until we know whether we're going to be using the panel's native mode or the user mode directly. Doing otherwise means X clients using xf86vidmode/xrandr will get a protocol error (and often self terminate as a result) when the kernel refuses to use the requested mode with the DBLSCAN flag. To undo the regression we'll move the DBLSCAN checks into the connector->mode_valid() and encoder->compute_config() hooks.
