Hi,
While testing the final 3.15, I noticed that "iwlist wlan0 scanning"
cannot find anything on my WRT54GL router anymore:
# iwlist wlan0 scanning
wlan0 No scan results
I bisected this to:
3afc2167f60a327a2c1e1e2600ef209a3c2b75b7 is the first bad commit
commit 3afc2167f60a327a2c1e1e2600ef209a3c2b75b7

cfg80211/mac80211: ignore signal if the frame was heard on wrong channel
Test case: I simply test it after the boot as follows:
modprobe b43
ifconfig wlan0 up
iwlist wlan0 scanning
Any ideas?

Check that the driver reports the channel the probe was heard on?
Another driver hit this and was fixed:
at76c50x: fix scan does not work with latest mac80211

It would also be helpful to report what device you have as shown by 'lspci -nn'.
This problem does not occur with my BCM4312 with PCI ID 14e4:4315.

I believe it's BCM5352E SoC wth G-PHY rev 7 and radio 0x2050 rev 2. Is
that correct? Provide us a boot log.

I've reproduced this on my G-PHY rev 8. This is a bug caused by the:
status.freq = chanid + 2400;
It results in the:
[ 1500.651877] Got chanid:3 set freq:2403
[ 1500.719688] Got chanid:4 set freq:2404
[ 1500.788645] Got chanid:5 set freq:2405
[ 1500.857630] Got chanid:6 set freq:2406
[ 1500.936061] Got chanid:7 set freq:2407
[ 1500.973772] Got chanid:8 set freq:2408
[ 1501.084351] Got chanid:9 set freq:2409
I'll submit a fix.

Yes, it's:
[ 9.460000] b43-phy0: Broadcom 5352 WLAN found (core revision 9)
[ 9.520000] b43-phy0: Found PHY: Analog 2, Type 2 (G), Revision 7
I confirm your patch fixes the issue, thanks.
