However, drm_dev->max_vblank_count is a member unique to vendor's DRM driver but in case of ARM DRM, some CRTC devices don't provide the frame counter value. As a result, this patch made extension and clone mode not working. Instead of this patch, we may need separated max_vblank_count which belongs to each CRTC device, or need to implement frame counter emulation for them who don't support HW frame counter.
