[PATCH v2] USB: serial: option: the patch is meant to support LARA-R6 Cat 1 and LARA-L6 CAT 4 module family.

[Davide Tronchin]

The LARA-R6 module old PID (defined as: UBLOX_PRODUCT_R6XX
0x90fa) has been removed. The new LARA-R6 (00B) definition uses 0x908b PID
and the reservation of port 3 is not needed anymore.

LARA-R6 00B USB composition exposes the following interfaces:
If 0: Diagnostic
If 1: AT parser
If 2: AT parser
If 3: AT parser/alternative functions

LARA-L6 module can be configured in three different USB modes:
* Default mode (Vendor  ID: 0x1546 Product ID: 0x1341) with 4 serial
interfaces
* RmNet mode (Vendor  ID: 0x1546 Product ID: 0x1342) with 4 serial
interfaces and 1 RmNet virtual network interface
* CDC-ECM mode (Vendor  ID: 0x1546 Product ID: 0x1343) with 4 serial
interface and 1 CDC-ECM virtual network interface

In default mode LARA-L6 exposes the following interfaces:
If 0: Diagnostic
If 1: AT parser
If 2: AT parser
If 3: AT parser/alternative functions

In RmNet mode LARA-L6 exposes the following interfaces:
If 0: Diagnostic
If 1: AT parser
If 2: AT parser
If 3: AT parset/alternative functions
If 4: RMNET interface

In CDC-ECM mode LARA-L6 exposes the following interfaces:
If 0: Diagnostic
If 1: AT parser
If 2: AT parser
If 3: AT parset/alternative functions
If 4: CDC-ECM interface

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

Your v2 patch does still not take into account that there are other 
companies re-selling this Qualcomm hardware and having a QMI direct net 
interface which you must blacklist when you add option support for this 
vid:pid.

Greg already mentioned the missing changelog here.

Also make sure to CC anyone that helps you with you review when
resending (i.e. Lars in this case).

And do remember to CC the maintainer, that is, me.
