Sure Andy, I can do as you suggest but i am confused now because on
another patch i've got "Acked-and-tested-by" only i.e. just one single
tag. So for consistency, what should i do? I also noticed that this tag
is used about 59 times in Linux kernel and i even found one
"Reported-Acked-and-Tested-by" too :) though i understand these may not
be acceptable by all Maintainers. So, please guide.
