From: Yegor Yefremov <yegorslists@xxxxxxxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 7b5939ba591e9affbe4f336935b0985fd250a2b3 upstream.
This device provides QMI and ethernet functionality via a standard CDC
ethernet descriptor. But when driven by cdc_ether, the QMI
functionality is unavailable because only cdc_ether can claim the USB
interface. Thus blacklist the device in cdc_ether and add its IDs to
qmi_wwan, which enables both QMI and ethernet simultaneously.
