[PATCH] hwmon: (nct7802) Fix integer overflow seen when writing voltage limits

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
