net: fix sparse warning in sk_dst_set()
sk_dst_cache has __rcu annotation, so we need a cast to avoid following sparse error : include/net/sock.h:1774:19: warning: incorrect type in initializer (different address spaces) include/net/sock.h:1774:19: expected struct dst_entry [noderef] <asn:4>*__ret include/net/sock.h:1774:19: got struct dst_entry *dst Signed-off-by: Eric Dumazet <edumazet@google.com> Reported-by: kbuild test robot <fengguang.wu@intel.com> Fixes: 7f502361531e ("ipv4: irq safe sk_dst_[re]set() and ipv4_sk_update_pmtu() fix") Signed-off-by: David S. Miller <davem@davemloft.net>
