Subject: qmi_wwan/cdc_ether: add device ID for HP lt2523 (Novatel E371) WWAN card

From: Bj�rn Mork <[email protected]>

[ Upstream commit 5b9f57516337b523f7466a53939aaaea7b78141b ]

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")
