[ Upstream commit 41a0be3f8f6be893860b991eb10c47fc3ee09d7f ]
Sparse complaints 3 times about: net/smc/smc_ib.c:203:52: warning: incorrect type in argument 1 (different address spaces) net/smc/smc_ib.c:203:52: expected struct net_device const *dev net/smc/smc_ib.c:203:52: got struct net_device [noderef] __rcu *const ndev
Fix that by using the existing and validated ndev variable instead of accessing attr->ndev directly.
