Hi,
The fix is right, but a couple of small changes:

The indentation here is not right. It was wrong already, but lets
seize the moment and fix it. This is how it should look like:
if (addr->a.sa.sa_family == AF_INET6 &&
ipv6_addr_equal(&addr->a.v6.sin6_addr,
&ifa->addr) &&
addr->a.v6.sin6_scope_id == ifa->idev->dev->ifindex) {
Thanks,
