3.5.7.21 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold <jhovold@xxxxxxxxx>
commit ff8a43c10f1440f07a5faca0c1556921259f7f76 upstream.
Make sure to fail properly if the device is not accepted during attach
in order to avoid null-pointer derefs (of missing interface private
data) at disconnect or release.
