It is not so easy, the function is exported at file
drivers/staging/rtl8192u/ieee80211/ieee80211.h and used at
drivers/staging/rtl8192u/ieee80211/ieee80211_module.c line 179 with
several other "null" functions, it seems a dirty trick to force module
loading:
/* These function were added to load crypte module autoly */
    ieee80211_tkip_null();
    ieee80211_wep_null();
    ieee80211_ccmp_null();

I guess all this stuff should be rewritten to force the autoload
properly but I don't have the knowledge to fix all this.
Sorry Greg :-(
