Question on stopping ath dmesg output spam

[waltfeasel@gmail.com]

First off thank you to all of you for your work in letting me run linux
on my system! It really is greatly appreciated! It has come a long ways
from the early 90's due to everyone sharing their skills and
contributing. Sadly the below is driving me nuts for some reason and I
am at a loss on how to remedy it myself so I seek your wisdom.

I really would like to find a way to stop the repeated messages from my
wireless device in dmesg. 
It works fine and I have never had an issue with it before. I have
updated to kernel ver 4.15-rc7 and could not find anything in
configuring to stop this behavior. 
It also does this with the latest 4.14.0-0.bpo.2-amd64 kernel from
Debian so I don't believe it is something I have or havn't done but I
have been wrong more than once when confident I was right.

Most of things I have found refer to getting the Qualcomm Atheros
AR9485 Wireless Network Adapter working on a system and do not fix the
repeated spamming of this message.

Is there something I need to fix or if this is normal behavior is there
a way I can send this to the black hole (/dev/null) it belongs in?

Thank you for any insight,

Walt
