Subject: [PATCH v1] hwmon: (scpi-hwmon) shows the negative temperature properly
Date:   Fri, 21 May 2021 20:42:04 +0800

The scpi hwmon shows the sub-zero temperature in an unsigned integer,
which would confuse the users when the machine works in low temperature
environment. This shows the sub-zero temperature in an signed value and
users can get it properly from sensors.
