This should be in the mac80211 patch.

This is causing a bunch of compiler warnings (warning: enumeration value
‘NL80211_IFTYPE_OCB’ not handled in switch, e.g. in mac80211/iface.c)
which I think you should address in this patch. That'll mean that you
modify even mac80211 and potentially some drivers, but I think that's
the right thing to do in this patch since it's the one changing the API
to introduce the new value.
The later patch can then add functionality to those new case labels in
mac80211 (this one of course adds it in cfg80211). For this patch they
should be with the error case that will typically exist.

This check isn't necessary,

it's also done in this function.
I think there's one thing you forgot in this patch, namely
__cfg80211_leave() which you also need to make the __ version of the
leave function non-static for due to locking.
I noticed that the switch statement there has a default case - I'll
remove that, so be sure to rebase on mac80211-next.
