3.16.7-ckt20 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Arik Nemtsov <arik@xxxxxxxxxx>
commit 1a3fe0b2b6778b7866e2b3f5c9a299d5e9bbd89c upstream.
During the CT-kill exit flow, the card is powered up and partially
initialized to check if the temperature is already low enough.
Unfortunately the init bails early because the CT-kill flag is set.
Make the code bail early only for HW RF-kill, as was intended by the
author. CT-kill is self-imposed and is not really RF-kill.
Fixes: 31b8b343e019 ("iwlwifi: fix RFkill while calibrating")
