Subject: [PATCH 3/6 net-next] net: Convert proto_ops bind() callbacks to use sockaddr_unspec
Update all struct proto_ops bind() callback function prototypes from
"struct sockaddr *" to "struct sockaddr_unspec *" to avoid lying to the
compiler about object sizes. Calls into struct proto handlers gain casts
that will be removed in the struct proto conversion patch.
No binary changes expected.
