  drm/exynos: replace request_threaded_irq with devm function
  drm/exynos: remove unnecessary devm_kfree
  drm/exynos: fix build warnings from ipp fimc
  drm/exynos: cleanup device pointer usages
  drm/exynos: wait for the completion of pending page flip
  drm/exynos: use drm_send_vblank_event() helper
  drm/exynos: page flip fixes
  drm/exynos: exynos_hdmi: Pass correct pointer to free_irq()
  drm/exynos: exynos_drm_ipp: Fix incorrect usage of IS_ERR_OR_NULL
