[OpenWrt-Devel] [PATCH] mac80211: ath10k Suppress 'failed to process fft' warning messages.

[Matti Laakso]

> When using DFS channels on Ath10k kernel log has warning message 'failed
> to process fft', typically when under medium/heavy traffic.  Ticket
> https://dev.openwrt.org/ticket/19316 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.

Looks good to me. Could you also send a patch to the ath10k mailing list
