And now you claim to be a Samsung representative again, I think your
country has some bad liable laws you might wish to watch out for...

This isn't going to go very far, so I'll just not respond anymore, it's
not going to be productive, and given that I don't see your name on the
code here, I don't see why I need to.

Please stick to technical discussions about the code on the kernel
mailing lists.  Legal discussions can be left up to the lawyers, of
which we are not.
