From ed1b6e99b5e64d2b9cdf764754a072c7fdc1c3c4 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 18 Mar 2010 09:58:27 -0700 Subject: iwlwifi: remove noise reporting We go to great lengths to calculate this value that is never used by mac80211. Additionally, it is now deprecated by mac80211 and is causing driver compilation to give warnings.
