Users of API provided by THERMAL_OF config may suffer when CONFIG_THERMAL=y, causing linking issues, such as: drivers/built-in.o: In function `lm75_remove': lm75.c:(.text+0x12bd8c): undefined reference to `thermal_zone_of_sensor_unregister' drivers/built-in.o: In function `lm75_probe': lm75.c:(.text+0x12c123): undefined reference to `thermal_zone_of_sensor_register' Therefore, this patch limits the compilation build to always have THERMAL=y, whenever THERMAL_OF=y. In this way, whenever the API user is built, if THERMAL_OF=y, the build shall have the full thermal support, otherwise, the thermal API will provide stubs.
