Subject: hwmon: (ds620) Fix overflows seen when writing temperature limits
From: Guenter Roeck <linux@roeck-us.net>
commit e36ce99ee0815d7919a7b589bfb66f3de50b6bc7 upstream.
Module test reports:
temp1_max: Suspected overflow: [160000 vs. 0]
temp1_min: Suspected overflow: [160000 vs. 0]
This is seen because the values passed when writing temperature limits
are unbound.
