Subject: [PATCH net-next 16/23] tipc: Eliminate useless check when network address is assigned

From: Allan Stephens <allan.stephens@...driver.com>

Gets rid of an unnecessary check in the routine that updates the port id
of a node's name publications when the node is assigned a network address,
since the routine is only invoked if the new address is different from
the existing one.
