imx-drm: flip_done timed out

Hi

I see the following error over and over and as a result a black screen :/

[drm:drm_atomic_helper_commit_cleanup_done] *ERROR* [CRTC:24:crtc-0] flip_done timed out

I am on latest longterm (4.9.31) with this four imx-drm patches atop:

Maybe my patches got replaced by a newer version or are there other patches I need to fix this? It would also quite nice if fixes for this problem could land in 4.9.x series.
