[MM 07] Huawei plugin: "Failed to find primary port"

[Bjørn Mork <bjorn mork no>]

Hello,

just got a new Huawei device here with 2 AT ports, 1 QCDM port and 1
QMI/wwan port.  They seem to be discovered OK, but for some reason the
modem creation fails with the message "Failed to find primary port":
