Subject: [PATCH drm-misc-next v2 2/9] drm/fsl-dcu: replace drm->dev_private with drm_to_fsl_dcu_drm_dev()
Using drm_device->dev_private is deprecated. Since we've switched to
devm_drm_dev_alloc(), struct drm_device is now embedded in struct
malidp_drm, hence we can use container_of() to get the struct drm_device
instance instead.
