Subject: net: fix sparse warning in sk_dst_set()
From: Eric Dumazet <edumazet@xxxxxxxxxx>
[ Upstream commit 5925a0555bdaf0b396a84318cbc21ba085f6c0d3 ]
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
