Rafael J. Wysocki 54d94009cb thermal: gov_bang_bang: Fix possible cooling device state ping-pong 
The current behavior of thermal_zone_trip_update() in the bang-bang
thermal governor may be problematic for trip points with 0 hysteresis,
because when the zone temperature reaches the trip temperature and
stays there, it will then cause the cooling device go "on" and "off"
alternately, which is not desirable.

Address this by requiring the zone temperature to actually fall below
trip->temperature - trip->hysteresis for the cooling device to go off.
