NVIDIA Tegra30 thermal sensor driver has a hardware-controlled CPU cooling
feature that halves CPU frequency once a specified trip point is breached.
In order to account the hardware state transitions, which are reported by
interrupt, the sensor driver needs to report the cooling state transition
and this is done by thermal_cooling_device_stats_update(). The sensor
driver could be compiled as a loadable driver module, but this API
function isn't exported, hence export it.
