Surely, but so how would things go? Scott said not fit for him. And he was
gonna to write a new patch(Oh, that is what I have been doing.....,and I really
donot think he need to do it)

This is the final version using UIO, and even Christophe had Reviewed-by,
https://lore.kernel.org/patchwork/patch/1226225/

If no ending reaches, I have to make a step forward to keep working with
the misc device version.

Thanks, and regards,
