Do not use the crtc_-prefixed display values from struct drm_display_mode for looking up the VBIOS mode. The fields contain raw values that the driver programs to hardware. They are affected by display settings like double-scan or interlace. Instead use the regular vdisplay and hdisplay fields for lookup. As the programmed values can now differ from the values used for lookup, set struct drm_display_mode.crtc_vdisplay and .crtc_hdisplay from the VBIOS mode.
