[PATCH] RDMA/addr: potential uninitialized variable in ib_nl_process_good_ip_rsep()

[Dan Carpenter]

The nla_len() is less than or equal to 16.  If it's less than 16 then
end of the "gid" buffer is uninitialized.

Fixes: ae43f8286730 ("IB/core: Add IP to GID netlink offload")

I just spotted this in review.  I think it's a bug but I'm not 100%.
