updated hwmon example

gsc

@@ -338 +338 @@
 A Linux 'Hardware Monitor' ({{{hwmon}}}) driver is available  which provides simple standard access to the above temperature/voltage registers via sysfs. The arguments have been given labels which define the source. The user can “cat” the label to determine the source. The hwmon will be found in /sys/class/hwmon/hwmonx where x is a number. Check all hwmonx directories, starting with x=0 and then x=1 until identifying the correct hwmon where the values are contained. 
 
-Example ran on a GW62xx using Ubuntu Bionic:
-{{{
-cd /sys/class/hwmon/hwmon1
-for F in *;do echo -n $F: ;cat $F;done

+{{{
+cd /sys/class/hwmon/hwmon0
