From 471d60fe594ed1a7ae28a3f911d1200ae51efbdc Mon Sep 17 00:00:00 2001 From: Inki Dae Date: Tue, 11 Sep 2012 16:35:23 +0900 Subject: [PATCH] drm/exynos: fix duplicated mutex lock issue exynos_drm_crtc_dpms function doesn't need mutex lock because mutex lock was called by drm framework so this patch removes mutex lock call from that function to avoid duplicated mutex locking.
