The mlx5 driver and some other OFED bits use a somewhat dubious pattern of: struct foo { uint64_t arg[0]; /* Real members of a struct */ }; The code then treats 'arg' as if it were really a kind of union such that foo.arg[N] functions similarly to (uint64_t *)foo[N]. This uses of foo.arg[N] then trigger this warning. No real bugs were found by this warning though, so just turn it off globally.
