+From 49cb13fcaf8aba657bd68e0da72311428db33161 Mon Sep 17 00:00:00 2001

+Subject: [PATCH 0442/4131] drm/amd/display: Refactor use_lut() from dce110 to
+ dce
+
+use_lut() checks if the input surface's pixel format is compatible with
+a 256 entry LUT. This function can be used across different versions and
+not just dce11.
