Marking the structs as const is fine, but marking them __initconst is
not. The GPIO LED driver can be built as a module, which means it can
be loaded after the init sections have gone away. If that happens,
then we de-reference the pointer to memory that has been freed.

Please re-spin your patch set without the __initconst marking.
