From: Guenter Roeck <linux@xxxxxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
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.
