[PATCH 070/115] qmi_wwan/cdc_ether: add device IDs for Dell 5804 (Novatel E371) WWAN card

[Luis Henriques]

3.5.7.13 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Williams <dcbw@xxxxxxxxxx>

commit 7fdb7846c9ca6fc06e380de0976a1228703b498a upstream.

A rebranded Novatel E371 for AT&T's LTE bands.  qmi_wwan should drive this
device, while cdc_ether should ignore it.  Even though the USB descriptors
are plain CDC-ETHER that USB interface is a QMI interface.
