--- Comment #9 from Oldřich Jedlička oldium.pro@seznam.cz 2011-02-24 10:54:32 --- I'm personally not convinced that number 0 is the way to go, because it is quite close to normal temperatures. It looks like a bug in interface and that it should return -EINVAL. I know that the interface shouldn't change whenever possible, but this looks like a real interface bug. I also guess it is nowhere defined that 0°C means "OFF".
And, by the way, think about the cooling with liquid nitrogen (on some advanced gamer PCs). Is 0°C out of range? Another, maybe more important, question - is 0°C out of the valid value range of the sensor?
Just my 2 cents, ignore me if I said something wrong :-)
