Subject: USB: keyspan: fix null-deref at disconnect and release
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.
