Subject: [RESENT PATCH net,stable] qmi_wwan/cdc_ether: add device ID for HP lt2523 (Novatel E371) WWAN card

Another rebranded Novatel E371.  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.  Ref commit 7fdb7846c9ca
("qmi_wwan/cdc_ether: add device IDs for Dell 5804 (Novatel E371) WWAN
card")

Resending with correct author and to address. I didn't manage to spell
kernel correctly... I guess I should have had one more cup of coffee
this morning.
