Should be:
#ifdef CONFIG_OF
static const struct of_device_id altera_ps2_match[] = {
{ .compatible = "ALTR,ps2-1.0", },
{},
}
MODULE_DEVICE_TABLE(of, altera_ps2_match);
#else /* CONFIG_OF */
#define altera_ps2_match NULL
#endif /* CONFIG_OF */
Otherwise the driver will be advertising that it provides device tree
support when CONFIG_OF is disabled.
Otherwise, looks good to me. Feel free to add my acked-by line.
