Subject: hwmon: (nct7802) Fix integer overflow seen when writing voltage limits
From: Guenter Roeck <linux@xxxxxxxxxxxx>
commit 9200bc4c28cd8992eb5379345abd6b4f0c93df16 upstream.
Writing a large value into a voltage limit attribute can result
in an overflow due to an auto-conversion from unsigned long to
unsigned int.
