Hi, This series contains two independent fixes for connector property updates in amdgpu_dm.
The first patch fixes a reproduced NULL-stream dereference and is marked for stable. The second avoids the visible panel blank caused by modesetting for every ABM level change. This is useful for desktop environments that want to adjust ABM dynamically for AC, battery and low-battery profiles without making the screen go black briefly on every profile transition. It would be nice to have the ABM fix in stable kernels too, but I am not sure whether this behavior issue justifies a stable backport. I therefore kept its Fixes tag but did not explicitly Cc stable.
