From 912-hwmon-lm90-expose-to-thermal-fw-via-DT.patch:
"This patch adds to lm90 temperature sensor the possibility
to expose itself as thermal zone device, registered on the
thermal framework.
The thermal zone is built only if a device tree node
describing a thermal zone for this sensor is present
inside the lm90 DT node. Otherwise, the driver behavior
will be the same."
