Subject[PATCH 3.12 008/181] tipc: fix memory leak of publications
Date
From: Ying Xue <ying.xue@windriver.com>

3.12-stable review patch. If anyone has any objections, please let me know.

===============

commit 1621b94d2a655c8548ddbdfc8ccf907a5bbdc860 upstream.

Commit 1bb8dce57f4d15233688c68990852a10eb1cd79f ("tipc: fix memory
leak during module removal") introduced a memory leak issue: when
name table is stopped, it's forgotten that publication instances are
freed properly. Additionally the useless "continue" statement in
tipc_nametbl_stop() is removed as well.
