Subject: [PATCH 4/7 net-next-2.6] tipc: Eliminate improper use of TIPC_OK error code
This patch corrects many places where TIPC routines indicated
successful completion by returning TIPC_OK instead of 0.
(The TIPC_OK symbol has the value 0, but it should only be used
in contexts that deal with the error code field of a TIPC
message header.)
