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

------------------

From: Arnd Bergmann <a...@arndb.de>

commit acbf76ee05067c3942852019993f7beb69a0f45f upstream.

dtc complains about the lack of #coolin-cells properties for the
CPU nodes that are referred to as "cooling-device":

arch/arm64/boot/dts/mediatek/mt8173-evb.dtb: Warning (cooling_device_property): 
Missing property '#cooling-cells' in node /cpus/cpu@0 or bad phandle (referred 
from /thermal-zones/cpu_thermal/cooling-maps/map@0:cooling-device[0])
arch/arm64/boot/dts/mediatek/mt8173-evb.dtb: Warning (cooling_device_property): 
Missing property '#cooling-cells' in node /cpus/cpu@100 or bad phandle 
(referred from /thermal-zones/cpu_thermal/cooling-maps/map@1:cooling-device[0])

Apparently this property must be '<2>' to match the binding.
