cfg80211: don't export ieee80211_get_channel
This patch makes ieee80211_get_channel a static inline defined in cfg80211's header file which simply calls __ieee80211_get_channel to avoid symbol clashes with the ieee80211 code. The problem was pointed out by David Miller, thanks! Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Cc: David Miller <davem@davemloft.net> Signed-off-by: John W.
