 The GEM core provides a helper method drm_gem_mmap() to
 handle object mapping. The method can be set directly as the mmap file
 operation handler. It will look up the GEM object based on the offset
-value and set the VMA operations to the :c:type:`struct drm_driver

+value and set the VMA operations to the :c:type:`struct drm_gem_object_funcs

 userspace, but relies on the driver-provided fault handler to map pages
 individually.
