Since you use "SF Markus Elfring", this patch should start with:

From: Markus Elfring <elfring@users.sourceforge.net>

We don't care that you used a sourceforge.net address. Or has SF another
meaning?

Side note: I guess the coccinelle script you use just skips cases like
    if (sym) {
        sym_calc_value(sym);
        do_foo_bar():
    }

Or did you filter those manually?
