With the correct change to qmi_wwan.c it now creates /dev/cdc-wdm0 and uses
QMI mode.
Not fully there yet, though, I tried --3gpp-scan and the modem is listed as
disabled:
linaro@linaro-gnome:~$ sudo mmcli -m 0 --3gpp-scan
error: modem not enabled yet
Looking at the modem state:
linaro@linaro-gnome:~$ sudo mmcli -m 0
