3.0-stable review patch. If anyone has any objections, please let me know.
------------------ From: "[email protected]" <[email protected]> commit 5d5440a835710d09f0ef18da5000541ec98b537a upstream. URB unlinking is always racing with its completion and tx_complete may be called before or during running usb_unlink_urb, so tx_complete must not clear urb->dev since it will be used in unlink path, otherwise invalid memory accesses or usb device leak may be caused inside usb_unlink_urb.
