From bd953de94393ef2a00e893aa948cc7c4cb190d00 Mon Sep 17 00:00:00 2001 From: YoungJun Cho Date: Wed, 1 Oct 2014 15:19:07 +0900 Subject: [PATCH] drm/exynos: fimd: remove unnecessary waiting vblank routine The exynos_drm_crtc_dpms() waits until pended page flip queue is empty, calls the drm_vblank_off() then calls manager->ops->dpms() when mode is DRM_MODE_DPMS_OFF. The fimd_dpms() is one of manager->ops->dpms()s and finally calls fimd_window_suspend(). But there is no active window and vblank is already off when it is called. So addtional waiting vblank is not necessary any more.
