<pre>When using DFS channels on Ath10k kernel log has warning message 'failed
to process fft', typically when under medium/heavy traffic. Ticket
<a moz-do-not-send="true" href="https://dev.openwrt.org/ticket/19316">https://dev.openwrt.org/ticket/19316</a> discusses and concludes messages
are harmless. They do still contribute to log noise, so this patch
enables them only in driver debug mode. Hopefully this will stop people
like me worrying about them.
Tested on Archer C7

Looks good to me. Could you also send a patch to the ath10k
mailing list (against kvalo's ath git)?<br>

Yes shouldn't be a problem. It'll take me a few days to get the
opportunity to do so as busy occupied on other things.<br>
