All of these 10 errors are repeated every 60 sec.

Catching up after the holidays ;-) Above chanspec values are invalid.
0x100e = channel 14/bw 20MHz. The 'iw list' output shows all these
channels are disabled. So who/what is trying to set these channels.
Scanning sets the channel in firmware. Is this initiated from hostapd?

Yeah, what userspace is running here? Looks like cfg80211_set_channel()
is only used for survey?

Couple of observations on the side:
* might be nice to have some "brcm" indication in that name :P

Indeed, having a function cfg80211_set_channel() in brcmfmac/cfg80211.c
is VERY misleading. I first though that is a cfg80211 function and
didn't understand Johannes' comment until I started grepping :) Can
someone fix that, please?

It is already on your queue for wireless-next. That was the 3rd patch for which you sent yourself a reminder earlier this week. You remember? ;-p
