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.
