Reviewed-by: Peter Maydell <peter.mayd...@linaro.org> I guess the other way to approach this would be to require the backing device and just set it up to be a "throw away output, never provide input" dummy if there isn't a real one. No idea if that's feasible though so NULL-guards seems reasonable. thanks -- PMM
