thermal: core: Allow orderly_poweroff to be called only once
thermal_zone_device_check --> thermal_zone_device_update --> handle_thermal_trip --> handle_critical_trips --> orderly_poweroff The above sequence happens every 250/500 mS based on the configuration. The orderly_poweroff function is getting called every 250/500 mS. With a full fledged file system it takes at least 5-10 Seconds to power off gracefully. In that period due to the thermal_zone_device_check triggering periodically the thermal work queues bombard with orderly_poweroff calls multiple times eventually leading to failures in gracefully powering off the system. Make sure that orderly_poweroff is called only once. Signed-off-by: Keerthy <j-keerthy@ti.com> Acked-by: Eduardo Valentin <edubezval@gmail.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
