Subject: [PATCH 3.12 36/84] tg3: Fix temperature reporting

From: Jean Delvare <jdelvare@...e.de>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit d3d11fe08ccc9bff174fc958722b5661f0932486 upstream.

The temperature registers appear to report values in degrees Celsius
while the hwmon API mandates values to be exposed in millidegrees
Celsius. Do the conversion so that the values reported by "sensors"
are correct.

Fixes: aed93e0bf493 ("tg3: Add hwmon support for temperature")
