    Subject[PATCH 4.14 218/237] USB: serial: option: add support for Cinterion MV31 with new baseline
    Date
    From: Slark Xiao <slark_xiao@163.com>

    commit 158f7585bfcea4aae0ad4128d032a80fec550df1 upstream.

    Adding support for Cinterion device MV31 with Qualcomm
    new baseline. Use different PIDs to separate it from
    previous base line products.
    All interfaces settings keep same as previous.

    Below is test evidence:

    D: Ver= 2.10 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs= 1
    P: Vendor=1e2d ProdID=00b9 Rev=04.14
    S: Manufacturer=Cinterion
    S: Product=Cinterion PID 0x00B9 USB Mobile Broadband
    S: SerialNumber=90418e79
    C: #Ifs= 4 Cfg#= 1 Atr=a0 MxPwr=500mA
    I: If#=0x0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=50 Driver=qmi_wwan
    I: If#=0x1 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=40 Driver=option
    I: If#=0x2 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=60 Driver=option
    I: If#=0x3 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=30 Driver=option

    For PID 00b8, interface 3 is GNSS port which don't use serial driver.
