Yeah. I do think that it'd be wrong for mac80211 to select LEDS_CLASS.
mac80211 implements the triggers and the lowlevel drivers implement the LED class device.
So mac80211 does not depend on LEDS_CLASS at all.

So p54 should probably introduce an automagic config option like b43 does, or it should do
something (ugly) like this:

#if defined(CONFIG_MAC80211_LEDS) && (defined(CONFIG_LEDS_CLASS) || defined(CONFIG_LEDS_CLASS_MODULE))
...
#endif
