This is already done though:
for (i = 0; i <= e - s; ++i) {
spin_lock_init(&sa_dev->port[i].ah_lock);
if (!rdma_cap_ib_sa(device, i + 1))
continue;
[..]
if (!count) {
ret = -EOPNOTSUPP;
goto free;
Why does it need to be duplicated? The other patches are all basically
like that too.
The add_one function should return -EOPNOTSUPP if it doesn't want to
run on this device and any supported checks should just be at the
front - this is how things work right now
