[PATCH 08/14] drm/exynos: create a fake mmap offset with gem creation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Don't create a fake mmap offset in exynos_drm_gem_dumb_map_offset. If
not, it will call drm_gem_create_mmap_offset whenever user requests
DRM_IOCTL_MODE_MAP_DUMB ioctl.
