The current code does not do this when compiled, which might be a
problem for distributors. Can you clarify the license?

Arnd,

Can you elaborate on this? I did a grep on the string "Redistributions
in binary form must reproduce the above copyright" and I could find
several instance of this. So I am not sure what you mean by "The current
code does not do this when compiled".

You write that the binary form of the code must produce the copyright
notice. I don't see any code that does this. If I was looking in the
wrong place, let me know.

Thanks Wingman for the response.

Arnd, by your statement 'I don't see any code that does this' do you expect a piece of code that embed the license in the binary image? If so, that seems weired to me.

Many of the drivers including this patch has the following statement in the license that is additional company specific license such as BSD that is applicable.

I read this as if the source is compiled and distributed as a binary either a kernel module ko file or as part of the kernel binary, this term must apply. Usually this is part of documentation that goes with the product AFAIK.

For example, we did a grep of the following
