    Subject[PATCH -next] wireless: TI wlxxx depends on MAC80211
    From: Randy Dunlap <rdunlap@xenotime.net>

    wl12xx build fails with many undefined symbol errors when MAC80211
    and CFG80211 are not enabled, so make WLCORE and WL12XX depend
    on MAC80211 (which already depends on CFG80211).

    Here are a few of the many build errors:

    drivers/built-in.o: In function `wl1271_register_hw':
    main.c:(.text+0x4197cd): undefined reference to `ieee80211_register_hw'
