Subject: [PATCH net-next 09/17] tipc: Eliminate unnecessary locking when starting topology service

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

Modifies the initialization code for TIPC's topology service to
avoid taking the spinlock protecting the subscriber list, since
there is no need to do this.
