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. Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
