<pre>When using DFS channels on Ath10k kernel log has warning message 'failed
to process fft', typically when under medium/heavy traffic. Ticket
<a 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>
