While we're at it, what about fixing two other drivers that obviously
have the same problem?

(BTW I didn't get an oops as I tried reproducing the problem, only a
"Trying to free nonexistent resource" in dmesg.)

I'm backporting these fixes to the lm_sensors2 CVS repository at the
moment, thanks for pointing them out.
