3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gustavo Zacarias <gustavo@xxxxxxxxxxxxxxx>
commit 8f173e22abf2258ddfa73f46eadbb6a6c29f1631 upstream.
Interface 1 on this device isn't for option to bind to otherwise an oops
on usb_wwan with log flooding will happen when accessing the port:
tty_release: ttyUSB1: read/write wait queue active!
It doesn't seem to respond to QMI if it's added to qmi_wwan so don't add
it there - it's likely used by the card reader.
