From 618c5a1236f179525d5f55beba23acf796581623 Mon Sep 17 00:00:00 2001

Subject: [PATCH] drm/amd/display: Only revalidate bandwidth on medium and fast
updates
[Why]
Changes that are fast don't require updating DLG parameters making
this call unnecessary. Considering this is an expensive call it should
not be done on every flip.
[How]
Guard the validation to only happen if update type isn't FAST.
