The sun4i-ts driver has had a dependency on the thermal code since it was first merged, but this is not currently enforced in Kconfig, so in some randconfig builds we get
drivers/built-in.o: In function `sun4i_ts_remove': :(.text+0x2376f4): undefined reference to `thermal_zone_of_sensor_unregister' drivers/built-in.o: In function `sun4i_ts_probe': :(.text+0x237a94): undefined reference to `thermal_zone_of_sensor_register' :(.text+0x237c00): undefined reference to `thermal_zone_of_sensor_unregister'
We need the dependency on THERMAL in order to ensure that this driver becomes a loadable module if the thermal support itself is modular, while the dependency on THERMAL_OF is a runtime dependency and the driver will still build but not work if it is missing.
