From 4a3ffedda2bdadf7ae315ae5f5f74477635d6bd6 Mon Sep 17 00:00:00 2001 From: Joonyoung Shim Date: Thu, 18 Sep 2014 17:50:35 +0900 Subject: drm/exynos: factor out initial setting of each driver From fimd driver and vidi driver, dev->irq_enabled and dev->vblank_disable_allowed are set and also mixer needs them even if missed. It's duplicated so set them when loads drm driver.
