    Thermal: do not clear passive state during system sleep · 964f4843

    commit ff140fea ("Thermal: handle thermal zone device properly
    during system sleep") added PM hook to call thermal zone reset during
    sleep. However resetting thermal zone will also clear the passive state
    and thus cancel the polling queue which leads the passive cooling device
    state not being cleared properly after sleep.
    
    thermal_pm_notify => thermal_zone_device_reset set passive to 0
    thermal_zone_trip_update will skip update passive as `old_target ==
    instance->target'.
    monitor_thermal_zone => thermal_zone_device_set_polling will cancel
    tz->poll_queue, so the cooling device state will not be changed
    afterwards.
