4.20-stable review patch. If anyone has any objections, please let me know. ------------------ [ Upstream commit d56c19d07e0bc3ceff366a49b7d7a2440c967b1b ] By defaul of-based thermal driver do not enable hwmon. This patch does this explicitly, so that the temperature can be read through the common hwmon sysfs.
