hwmon: (k10temp) Only apply temperature offset if result is positive
A user reports a really bad temperature on Ryzen 1950X. k10temp-pci-00cb Adapter: PCI adapter temp1: +4294948.3°C (high = +70.0°C) This will happen if the temperature reported by the chip is lower than the offset temperature. This has been seen in the field if "Sense MI Skew" and/or "Sense MI Offset" BIOS parameters were set to unexpected values. Let's report a temperature of 0 degrees C in that case. Fixes: 1b50b776 ("hwmon: (k10temp) Add support for temperature offsets") Signed-off-by: Guenter Roeck <linux@roeck-us.net>
