Subject:ACPI: Set FAN device to correct state in boot phase
From: Zhao Yakui <yakui.zhao@intel.com>

On some laptops when ACPI FAN driver is loaded, maybe the FAN device will be
turned on. But if the temperature is below the threshold, the corresponding
FAN device should be turned off in the course of loading thermal driver.

So it is necessary to set the FAN device to the correct state in course of loading
the thermal driver.
