Zhao: this fix is great. My development machine was running some
ancient distro with kernel 2.6.22, so I couldn't test it earlier.

For a long time I got problem with finding AP on channel 13. I reported it in:
cfg80211: use DS or HT operation IEs to determine BSS channel"

I did 10 tests *without* your patch. wpa_supplicant had to scan 43,
33, 7, 2, 46, 12, 7, 32, 6, 6 times to find my AP on channel 13.
With your patch wpa_supplicant finds it in scanning results after the first try!

Thanks a lot for finding and fixing it!
