The commit d931589c ("drm/exynos: remove DRM_EXYNOS_GEM_MAP_OFFSET ioctl") removed it same with the ioctl that this patch adds. The reason that removed DRM_EXYNOS_GEM_MAP_OFFSET was we could use DRM_IOCTL_MODE_MAP_DUMB. Both did exactly same thing. Now we again will revive it as DRM_EXYNOS_GEM_MAP because of render node. DRM_IOCTL_MODE_MAP_DUMB isn't permitted in render node. Signed-off-by: Joonyoung Shim <jy0922.shim@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
