Please, can I have a positive/negative feedback about that? Thanks.

I can add it to the staging tree _if_ the code is under drivers/staging/ which I do not think your patch places the code at, right?

So if you wish to do that, I'd be glad to take it, but you need to have a list of things left to do to get it integrated into the "main" portion of the kernel. Do you have that at the moment?

thanks,
