From 873bbf2da278f253df9fa78acb8df83fb05c7c52 Mon Sep 17 00:00:00 2001 From: Alvin Lee Date: Wed, 7 Jun 2023 17:17:59 -0400 Subject: [PATCH] drm/amd/display: Clear update flags at end of flip Clear update flags so the next flip does not have any redundant programming (if a subsequent flip does not have a stream or plane update, the update flags are not cleared).
