Subject: [PATCH] Update pwmconfig

If sensor doesn't return any value (in my case it happen when fan got broken - look below) whole script gets messed up. "cut" latter in the script assume there are more values in $GOODFAN then there are really and "cut -d' ' -f$count" doesn't return proper value.

root@yaro-desktop2:/sys/class/hwmon# cat hwmon0/fan1_input
cat: hwmon0/fan1_input: Bad argument
