Everything looks fine, but I would redo the last part without
the last goto out. Using a goto back to single return reduces
readability.

	if (error)
               goto register_error;
        
	pm_runtime_set_memalloc_noio(dev, true);
	return 0;

register_error:
      device_del(dev);
device_add_error:
       put_device(dev);
       return error;
