commit8ece3173f8upstream. Make sure to drop the reference to the secure monitor device taken by of_find_device_by_node() when looking up its driver data on behalf of other drivers (e.g. during probe). Note that holding a reference to the platform device does not prevent its driver data from going away so there is no point in keeping the reference after the helper returns.
