    Subject[PATCH 4.18 18/35] USB: option: add support for DW5821e
    Date
    4.18-stable review patch.  If anyone has any objections, please let me know.

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

    From: Aleksander Morgado <aleksander@aleksander.es>

    commit 7bab01ecc6c43da882333c6db39741cb43677004 upstream.

    The device exposes AT, NMEA and DIAG ports in both USB configurations.

    The patch explicitly ignores interfaces 0 and 1, as they're bound to
    other drivers already; and also interface 6, which is a GNSS interface
    for which we don't have a driver yet.
