Subject: hwmon: (ds620) Fix overflows seen when writing temperature limits

From: Guenter Roeck <[email protected]>

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.
