Ok, I don't see it merged in the latest -mm (mmotm). Could you, Mark, Rafael,
sign off this version of the patch (Mark's + Rafael's fix)?

coretemp, suspend fix
It's not permitted to unregister device/cpu if frozen and going to sleep.
It causes deadlock on systems, where coretemp hwmon is loaded. Do it only
in non-freezed states instead.
