Subject: Re: [PATCH v2] USB: serial: option: add Luat Air72*U series products

If#= 2: AT
If#= 3: PPP + AT
If#= 4: Debug

Reference from the device documentation:
https://doc.openluat.com/wiki/21?wiki_page_id=2501

Should I send a v3 to include the serial interfaces information in the 
git message? This is my first time sending a patch to the kernel, please 
forgive me for not being particularly sure of the process.

Thanks,
