Hi,
thanks for taking my comments into consideration.


My point was something like:

	ret = devm_request_threaded_irq(dev, data->irq,
			loongson2_thermal_alarm_irq, loongson2_thermal_irq_thread,
			IRQF_ONESHOT, "loongson2_thermal", data);
	if (ret < 0)
		return dev_err_probe(dev, ret, "failed to request alarm irq\n");

But that  mostly a matter of taste. I don't think it worth a re-spin 
only for that.


However, I'll send another comment about the use of min() and max() in 
v11. I think it is not correct.
