From 64ea2992a29aa0bdc4eaf457351b063caafb6655 Mon Sep 17 00:00:00 2001 From: Sujith Manoharan Date: Mon, 10 Jun 2013 13:49:40 +0530 Subject: 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 Signed-off-by: John W.
