From a12ae6f937b04d618a837cbbe81c180053041634 Mon Sep 17 00:00:00 2001

Subject: [PATCH 2668/4131] drm/amd/display: Fix Freesync enablement
With our recent change to save Freesync properties as part
of the atomic state we removed the call to enable freesync
when the property is being set. Apparently that is still
needed.
