Hi Bagas Sanjaya, I'm not an employee of ZTE, just an ordinary developer. I really don't know all the details about community and ZTE, The reason why I cc cgel.zte@gmail.com is because the output of the script has the address . If there is any error in the format of the email, I will try my best to correct it. > > I was about to review documentation part of this patch, but due to > concerns above, I have to write this reply instead.
