Yes, you're right.
I should leave a message.. sorry.
I had been making many patches, I think, until last year.
But I didn't contribute to linux kernel for long time(maybe one year.. :-( )
And I made mistakes while sending patches.. I was breaking the working
code because of this.
So I want to start over from making minor patches like fixing coding style.
Now, this patch was taken by Greg.
And also I will try to fix other coding style first of this module.
(I had been fixing issues dgap module that was removed in linux-next
branch. dgnc has same issues what dgap has.
I can also fix issues in dgnc module.)
Thanks for comment.
regards,
Daeseok.
