Both the change of the position of the copyright note and the rewording contain a subtle but still significant change of meaning.
Now it seems as if Nvidia was the major copyright holder. Is this intentional?
I was not aware that the order actually implied anything. I would imagine the copyright dates and "git blame" output were more relevant since they pin-point specific changes, whereas copyright headers don't have the detail to convey the whole picture.
In this case, both "git log" and "git blame" certainly show that NVIDIA is the primary author of this code. I deliberately removed "Portions" because it was something uncommon and seems inaccurate. I don't recall why I changed the order; probably because I was editing a lot of files and just happened to paste the message there. I imagine the Samsung copyright notice is only there because the general structure of the file (set of functions implemented) was based on an existing driver, rather than because any of the non-boilerplate code was written by them.
Unfortunately we've (NVIDIA at least) been a little lax making sure the NVIDIA copyright messages are kept up-to-date when editing files, hence why this series had to change a lot of them for the first time recently. If we went back and re-wrote all of git history paying strict attention to the copyright notice dates and formatting, I imagine the set of copyright-related changes in this series would be much smaller.
