The remove_sta_debugfs callback in struct rate_control_ops is no longer used by any driver, as there is no need for it (the debugfs directory is already removed recursivly by the mac80211 core.) Because no one needs it, just remove it to keep anyone else from accidentally using it in the future. Cc: Johannes Berg <johannes@sipsolutions.net> Cc: "David S.
