openwrt15.05 failsafeモジュールを追加し、WEBログインエラー

最近新しいルータにopenwrt 15を移植する.05,failsafeモジュールを追加したことを発見した後、webログインは以下のエラーを提示した.

/usr/lib/lua/luci/dispatcher.lua:433: Failed to execute function dispatcher target for entry '/'.

/usr/lib/lua/luci/controller/failsafe/failsafeを開きます.luaファイル、検出

local fp
        luci.http.setfilehandler(
                function(meta, chunk, eof)
                        if not fp then
                                if meta and meta.name == "image" then
                                        fp = io.open(image_tmp, "w")
                                end
                        end
                        if chunk then
                                fp:write(chunk)
                        end
                        if eof then
                                ***fp:close()***
                        end
                end
        )

ここでのfp:cloase()はエラーを報告し、ここでの判断条件をif eof and fp thenに変更してテストOKとし、徹底的に修正するためにopenwrt-15.05/openwrt/package/feeds/luci/luci-mod-failsafe/luasrc/controller/failsafeを開き、この文書のif eof then判断条件をif eof and fp thenに変更すればよい.
