Thermal core could not read the temperature after registering the
thermal sensor with thermal_zone_of_sensor_register() because the driver
was not yet initialized.
The call trace looked like:
exynos_tmu_probe()
thermal_zone_of_sensor_register()
of_thermal_set_mode()
thermal_zone_device_update()
exynos_get_temp()
if (!data->tmu_read) return -EINVAL;
exynos_map_dt_data()
data->tmu_read = ...
This produced an error in dmesg:
thermal thermal_zone0: failed to read out thermal zone (-22)
Register the thermal_zone_device later, after parsing Device Tree and
enabling necessary clocks, but before calling exynos_tmu_initialize()
which uses the registered thermal_zone_device.
