Please don't top post and consider using dots instead of new lines ;)

I'm aware adding something new to the code doesn't give me all
Copyrights. The thing is the whole real content of the old file (one
line) was rewritten by this patch. That's why I replaced Copyright.

Just a note, rather than removeing copyright openwrt you should probably say 
parts are copyright openwrt and parts copyright lede


just because you added a bit doesn't give you sole copyright of the file :-)

but it does mean that openwrt doesn't own the copyright of the entire file any 
more either.


the git history can untangle this for anyone who cares.

But there is enough bad feelings going around, we don't need someone getting 
angry over copyright notices being removed.
