ath9k: Do not assign noise for NULL caldata
commit d3bcb7b24bbf09fde8405770e676fe0c11c79662 upstream. ah->noise is maintained globally and not per-channel. This is updated in the reset() routine after the NF history has been filled for the *current channel*, just before switching to the new channel. There is no need to do it inside getnf(), since ah->noise must contain a value for the new channel. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W.
