Are there any further configurations for this device that you need to
consider?
You reserve interface 6 below which doesn't even exist in the above
configuration.
Can you say something more about what the individual interfaces are used
for, for example, as was done here:
https://lore.kernel.org/all/TYZPR06MB4270D3394B8E3E0301738F6B86D09@TYZPR06MB4270.apcprd06.prod.outlook.com/

As mentioned above RSVD(6) looks wrong here.
Please move the comment to the first line of the entry, and move the
entry to the other Quectel entries using numerical PIDs (i.e. before
EM160R-GL).

Dear Johan,
The interface 6 is fixed to QMI WWAN in EM05-G modem. If I don't reserve it, it will matches the option driver, it's not correct.
I'll change the comments.

Hi,
This is the friendly patch-bot of Greg Kroah-Hartman. You have sent him
a patch that has triggered this response. He used to manually respond
to these common problems, but in order to save his sanity (he kept
writing the same thing over and over, yet to different people), I was
created. Hopefully you will not take offence and will fix the problem
in your patch and resubmit it so that it can be accepted into the Linux
kernel tree.
You are receiving this message because of the following common error(s)
as indicated below:
- This looks like a new version of a previously submitted patch, but you
did not list below the --- line any changes from the previous version.
Please read the section entitled "The canonical patch format" in the
kernel file, Documentation/SubmittingPatches for what needs to be done
here to properly describe this.
If you wish to discuss this problem further, or you have questions about
how to resolve this issue, please feel free to respond to this email and
Greg will reply once he has dug out from the pending patches received
from other developers.
thanks,
greg k-h's patch email bot
