Linux 3.15: WLAN regression on WRL54GL/B43?

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?
