-/* The next few functions are the call-back functions of the /proc/sys and

- 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. */
