From f8172eb3b28b2a497fcbabd7b2d9048ca2b585fc Mon Sep 17 00:00:00 2001 From: Andrzej Hajda Date: Wed, 15 Mar 2017 15:41:08 +0100 Subject: [PATCH] drm/exynos/decon5433: kill DECON_UPDATE workaround Since fixing CMU code (drm/exynos/decon5433: fix CMU programming) DECON started behave predictable and does not need special care during DECON_UPDATE writes.
