	drm_agp_free_memory(entry->handle);
	DRM_LOCK(dev);

	free(entry, DRM_MEM_AGPLISTS);

}

Example #2

int drm_agp_unbind(struct drm_device *dev, struct drm_agp_binding *request)
{
	drm_agp_mem_t     *entry;
	int retcode;

	if (!dev->agp || !dev->agp->acquired)
		return EINVAL;

	entry = drm_agp_lookup_entry(dev, (void *)request->handle);
	if (entry == NULL || !entry->bound)
		return EINVAL;

	retcode = drm_agp_unbind_memory(entry->handle);

	if (retcode == 0)
		entry->bound = 0;

	return retcode;
}
