thermal: Prevent polling from happening during system suspend
The thermal driver should use a freezable workqueue to schedule polling to prevent thermal_zone_device_update() from being run during system suspend, when the devices it relies on may be inactive. Make it use the system freezable workqueue for this purpose. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Len Brown <len.brown@intel.com>
