2016-06-27hwmon: (ina3221) Fix negative limitsGuenter Roeck1-7/+6
The result of an integer divide by an unsigned is undefined. This causes unexpected results when writing negative values into the limit registers. Maintain the shunt_resistors variables as signed integer to avoid the problem. Also, for simplicity and ease of use, clamp shunt resistor value on writes instead of rejecting bad values.
