-/* These funcion reads or writes a 'real' value (encoded by the combination

-   you must (before registering the ctl_table) set the extra2 field to the

-      void func(struct i2c_client *client, int operation, int ctl_name,
-                int *nrels_mag, long *results)
-   This last function can be called for three values of operation. If
-   operation equals SENSORS_PROC_REAL_INFO, the magnitude should be returned
-   in nrels_mag. If operation equals SENSORS_PROC_REAL_READ, values should
-   be read into results. nrels_mag should return the number of elements
-   read; the maximum number is put in it on entry. Finally, if operation
-   equals SENSORS_PROC_REAL_WRITE, the values in results should be
-   written to the chip. nrels_mag contains on entry the number of elements
-   found.
-   In all cases, client points to the client we wish to interact with,
-   and ctl_name is the SYSCTL id of the file we are accessing. */
