Subject: Any secret to use a salt_hash function?

Hi, is there any secret to use a salt_hash function?

The hash function returns something valid, but seems it is ignored. Any 
flag to adjust?

Thanks.

Some code below:
-------------

    static int salt_hash(void *salt) {
         unsigned char *s = salt;
         unsigned int hash = 5381;
         unsigned int i;

         for (i = 0; i < sizeof(sha512_salt); i++)
             hash = ((hash << 5) + hash) ^ s[i];

         return hash & (SALT_HASH_SIZE - 1);
    }

AND

    struct fmt_main fmt_opencl_cryptsha512 = {
    ...
                 binary_hash_6
             },
             salt_hash,
             set_salt,
             set_key,
