thermal: core: Reference count the zone in thermal_zone_get_by_id()
In the Linux kernel, the following vulnerability has been resolved: thermal: core: Reference count the zone in thermal_zone_get_by_id() There are places in the thermal netlink code where nothing prevents the thermal zone object from going away while being accessed after it has been returned by thermal_zone_get_by_id(). To address this, make thermal_zone_get_by_id() get a reference on the thermal zone device object to be returned with the help of get_device(), under thermal_list_lock, and adjust all of its callers to this change with the help of the cleanup.h infrastructure.
