I have tried to understand this couple of times, but always have ended
up giving up and leaving the patch in the queue to find a better time to
look a this.. Now that I'm trying to clean all the pending items, I
cannot really follow this explanation at all.. This function is
wpas_go_neg_complete(). It is called at the completion of GO Negotiation
which happens before there is any chance of even starting WPS PBC. As
such, this does not really make any sense to me.
If there is a case where this change is needed, please provide
wpa_supplicant debug logs with and without this change pointing out the
improvement. For now, I'll drop this patch and the 2/2 cleanup.
