Since staging driver wlan-ng uses function ieee80211_dsss_chan_to_freq,
This patch "ieee80211: remove function ieee80211_{dsss_chan_to_freq,
freq_to_dsss_chan}" should be applied later, when that staging-next
patch "staging: wlan-ng: replace function ieee80211_dsss_chan_to_freq()"
appear on wireless-next.
