Bug Description

SRU Justification:

Impact: repetitive log messages spam the console

How to reproduce: boot the board and watch the console being spammed every
2secs by these messages:

[ 2435.003417] ieee80211 phy0: device no longer idle - scanning
[ 2436.672180] ieee80211 phy0: device now idle

Fix: for the wifi part, turn off CONFIG_MAC80211_VERBOSE_DEBUG


Wifi driver appears to leave a:message every time it wakes up and then sleeps:

[ 2435.003417] ieee80211 phy0: device no longer idle - scanning
[ 2436.672180] ieee80211 phy0: device now idle

Appears every few seconds.

Also, sound configuration is leaving a lot of error messages as well:

the wifi debugging can be turned off commenting:


while the audio part seems a pulseaudio problem.
