Linville" , Johannes Berg Cc: linux-wireless@vger.kernel.org, Jouni Malinen Subject: [PATCH 4/4] nl80211: Check iftype in cfg80211 code Sender: linux-wireless-owner@vger.kernel.org List-ID: We do not want to require all the drivers using cfg80211 to need to do this. In addition, make the error values consistent by using EOPNOTSUPP instead of semi-random assortment of errno values.
