The interface changed.  Why is this so hard to understand?  Change it back! 
It's two lines of code, I expect.

I bet everyone's machine was previously reading zero.  Now it's reading random
crap.  Random crap which can lead userspace to think that the machine is
overheating, which could have fairly serious consequences.

We should never have made that temperature readable when the hardware is
disabled.  Now we have done so, we should return a safe and predictable result.
 Not random non-back-compatible crap!
