An incorrect sizeof is being used, struct rvt_ibport ** is not correct,
it should be struct rvt_ibport *. Note that since ** is the same size
as
* this is not causing any issues. Improve this fix by using
sizeof(*rdi->ports) as this allows us to not even reference the type
of the pointer. Also remove line breaks as the entire statement can
fit on one line.
