Hi,
since Linux 6.2-rc1 i noticed on my Raspberry Pi 3 B+
(arm/multi_v7_defconfig) the following new error messages appear, even
if there is no Wifi connection. I suspect this is not a real issue, so
it would nice to get the rid of it:

All of these 10 errors are repeated every 60 sec.
If i enable the debugging for brcmf_fil_cmd_data, i'm getting this:
[ 107.069199] brcmfmac: Firmware error: BCME_BADCHAN (-20)
