While at it, why not simply remove the "#if CONFIG_OF", the if (of_id), and
write simply this, without any ifs ? :
	pdata->is_slave = of_property_read_bool(pdev->dev.of_node,
						"spi-slave");

If CONFIG_OF=n, of_property_read_bool() is guaranteed to return false. If the
device is not found through devicetree, of_node == NULL and a false will
still be returned. And the last case is your bool read case (ie. when devicetree
probed the device).

Cheers.
