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.
