config THERMAL_HWMON
bool
prompt "Expose thermal sensors as hwmon device"
depends on HWMON=y || HWMON=THERMAL
default y
please check if the thermal subsystem is built in, while hwmon subsystem
is built as module.
you should either set CONFIG_HWMON=y, or set both CONFIG_HWMON and
CONFIG_THERMAL as module.
