4.16-stable review patch. If anyone has any objections, please let me know. ------------------ From: Hans de Goede <hdegoede@xxxxxxxxxx> [ Upstream commit 13b86f50eaaddaea4bdd2fe476fd12e6a0951add ] Starting with kernel 4.17 thermal_cooling_device_register() will call the get_max_state() op during register. Since we deref priv->priv in int3403_get_max_state() this means we must set priv->priv before calling thermal_cooling_device_register().
