Please work on simplifying & making topic more accurate.
You can drop "main.c:" and "This patch".
I don't think this patch really "removes unnecessary return". It looks
like you just dropped assignment/calculation done just before
returning value. That "using spatch tool" part is also misleading. You
don't really use that tool for removing it. More likely it was
noticed/suggested that that tool you use.
Please use commit message for describing your change and don't just
copy & paste topic. You can e.g. put into about "spatch" there
(instead of the topic).

Huh? Looks definitely wrong and I don't think it even compiles
anymore! Make sure to compile code after your change, to make sure it
does & there isn't any new warning.

Please rework your patch, *test it* and resend V2.

Also an extra line break above Signed-off-by is preferred. Look at
"git log" to get am overview.

I'm all for cleaning up code, but I don't really see how this
change improves the code.

What is the purpose of this change, won't this cause the file to fail
to compile?

Is the size variable used elsewhere? If not, it's declaration should
probably be removed.
Also, there should be a blank line before the return statement.
