So I am trying to submit some patches there. I had sent you the patch to review before greg asked me to do so. Maybe the patch I sent could be base64-encoded as per samsung mailing policy. From now onwards I will use gmail(atulraj.nith@xxxxxxxxx) till I get exception from encoding. I am sorry for all the trouble. I am cc:ing the patch to email address as asked by you. Thanks
