Each function must return the magnitude (power of 10 to divide the date
with) if it is called with operation==SENSORS_PROC_REAL_INFO. It must
put a maximum of *nrels elements in results reflecting the data of this
file, and set *nrels to the number it actually put in it, if operation==
SENSORS_PROC_REAL_READ. Finally, it must get upto *nrels elements from
results and write them to the chip, if operations==SENSORS_PROC_REAL_WRITE.
Note that on SENSORS_PROC_REAL_READ, I do not check whether results is
large enough (by checking the incoming value of *nrels). This is not very
good practice, but as long as you put less than about 5 values in results,
you can assume it is large enough. */
