All the non-drm patches have been acked by the respective maintainers. I'm now feeling comfortable to take this series into drm-misc-next and going to do it later this week. If anyone have more comments to add, then please do it now. It won't be possible to drop out patches from drm-misc once they will be merged. All further changes will have to be made on top of the applied patches. Thanks to all who reviewed this patchset! -- Best regards, Dmitry
