This fixes sparse warnings like the one below:

drivers/net/team/team.c:953:25: warning: incorrect type in return expression (different address spaces)
drivers/net/team/team.c:953:25:    expected struct netpoll_info *
drivers/net/team/team.c:953:25:    got struct netpoll_info [noderef] <asn:4>*npinfo
