+Subject: hwmon: (it87) Properly decode -128 degrees C temperature
+To: stable@kernel.org
+Message-ID: <20090313133404.79642fc4@hyperion.delvare>
+
+commit e267d25005c861fe6afda343f044536342c9f8b4 upstream
+
+The it87 driver is reporting -128 degrees C as +128 degrees C.
+That's not a terribly likely temperature value but let's still
+get it right, especially when it simplifies the code.
