I run the SmPL against the Linux kernel 2.6.32-rc2. In some cases there is
the __devinitdata is also specified. When adding "const" the __devinitdata has
to be also changed to __devinitconst. I tried like this, but something is needed
to tell spatch about "__devinitdata":

// <smpl>
@r@
identifier I1, I2, x;
@@
        struct I1 {
          ...
          const struct I2 *x;
          ...
        };
@s@
identifier r.I1, y;
identifier r.x, E;
@@
        struct I1 y = {
          .x = E,
        };
@c@
identifier r.I2;

        const struct I2 E[] = ... ;

        struct I2

@depends on !c && !i@
identifier r.I2;
identifier s.E;

+       const
        struct I2 E[] = ...;
// </smpl>

Here is the test c file:
---8<---- cut here ---8<---

struct A {
        int aa;
        const int ab;
        int ac;
};

struct B {
        int ba;
        const int bb;
};

struct C {
        const struct A *pa;
        struct B *pb;
};

struct A __devinitdata x[] = {
        {
                0,
                1,
                2
        }
};

struct B __devinitdata z[] = {
        {
                7,
                8,
        }
};

struct C __devinitdata q = {
        .pa = x,
        .pb = z,
};
---8<---- cut here ---8<---

The expected patch would be:
--- test4.c     2010-01-04 06:54:51.000000000 +0100
+++ /tmp/cocci-output-6242-194b66-test4.c       2010-01-04 07:11:11.000000000 
+0100
@@ -15,7 +15,7 @@ struct C {
        struct B *pb;

-struct A __devinitdata x[] = {
+const struct A __devinitconst x[] = {
        {
                0,
                1,

How can I express the "__devinitdata" in SmPL?
