4.2.8-ckt2 -stable review patch. If anyone has any objections, please let me know. ---8<------------------------------------------------------------ From: Martin Peres <martin.peres@free.fr> commit a814a29d7bbfdfe56fe1bb9641a185077066eb9f upstream. This is an oversight that made use of the trip-point-based fan managenent on cards that never expose those. This led the fan to stay at fan_min. Fortunately, the emergency code would kick when the temperature would reach 90°C.
