[PATCH 0/2] drm/amd/display: Fix streamless connector update and ABM modesets

[David Weber <weber.aulendorf@gmail.com>]

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.

David
