I suspect you could simplify this a bit by doing something like:

    const unsigned int *intbuf;

    if (IS_V4(inst->core)) {
        arr_sz = ARRAY_SIZE(intbuf_types_4xx);
        intbuf = intbuf_types_4xx;
    } else {
        arr_sz = ARRAY_SIZE(intbuf_types_1xx);
        intbuf = intbuf_types_1xx;
    }

    for (i = 0; i < arr_sz; i++) {
        ret = intbufs_set_buffer(inst, intbuf[i]);
        if (ret)
            goto error;
    }

These structures are being used in the next patch - wouldn't it make
more sense to move their declaration there as well?
