Noted.

I think I missed initialization of min_scaler and max_scaler in 
sun8i_vi_layer_atomic_check() in sun8i_vi_layer.c when I was reworking 
patches.

Will you fix patch with those two lines
min_scale = DRM_PLANE_HELPER_NO_SCALING;
max_scale = DRM_PLANE_HELPER_NO_SCALING;

or should I send new patch which fixes that or should I send new version of 
original patch?

Best regards,
Jernej
