    This says NULL is the identity function, which is not the same as:

    static void null_encrypt(void *ctx, u8 *dst, const u8 *src)
    { }

    In practice this code never gets called because cbc_process() has
    a special case for iv==NULL. But I'd rather see a semantically
    correct reference implementation. Or just leave .cia_encrypt=NULL.

    Am I missing something here ?
