Subject: Re: [PATCH] qmi_wwan/cdc_ether: add device IDs for Dell 5804 (Novatel
 E371) WWAN card

Just a side note on this. By default for this device, modprobe won't
load and assign the option driver. However, if cdc_ether is
blacklisted and you try to load option onto the device, it will try to
load the option driver onto where cdc_ether was being used, which will
cause the system to lock up. I'm not sure what needs to be done to
force qmi_wwan to take over cdc_ether without option grabbing these
IDs...
