Before assigning window data, we should check if the yuv2yuv vop-data is set at all, because it looks like it can otherwise reference something wrong, as I saw on my rk3188 today which ended up in a null pointer dereference in vop_plane_atomic_update when accessing the yuv2yuv data.

Fixes: 1c21aa8f2b68 ("drm/rockchip: Fix YUV buffers color rendering") Signed-off-by: Heiko Stuebner heiko@sntech.de

applied to drm-misc-next where the fixed commit also waits for the next merge-window.
