[PATCH] hwmon: Off-by-one error in fscpos driver
Coverity uncovered an off-by-one error in the fscpos driver, in function set_temp_reset(). Writing to the temp3_reset sysfs file will lead to an array overrun, in turn causing an I2C write to a random register of the FSC Poseidon chip. Additionally, writing to temp1_reset and temp2_reset will not work as expected. The fix is straightforward.
