-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.
