Subject: [PATCH 6/6] ARM: EXYNOS: removing exynos-drm device registration from
non-dt platforms
As exynos-drm is a software device, its registration is moved to the
exynos drm driver. This will provide generic solution for device registration
for dt and non-dt platforms. Corresponding patches are posted to dri-devel
list.
