Hi. I hope this is right place to ask question on SubmittingPatches. I would like to ask how correctly give the credits in the patch when I do forward-porting. There is some downstream kernel git where support of the some ARM board is implemented for 3.12. What I did was to take dts, adopted it for linux master and tested on upstream 3.18.1 (will also test with 3.19-rc), and found the board working. I don't know if initial authors ever send this to upstream, but GPL terms allows us to take this code right now. In the initial commit tree, the code I tested is belong to several different people, but I have to rebase the initial tree to take only tiny needed part, so I can not just resend initial commits. How should I properly fill "From:" field in the patch to specify initial authors correctly?
