From 154b4570d11ff7a6dbaec35efd8a9dd2d58f0662 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1751/2940] drm/amd/display: remove min reduction for abm 2.2
level 3
[Why]
Image brightness compensation for solid color full screen images is
expected to be optimal for ABM 2.2 at level 3. The min reduction that is
currently being enforced prevents this from being achieved.
[How]
Remove the min reduction for ABM 2.2 at level 3
