[TIPC]: Use tipc_port_unlock
The file net/tipc/port.c takes a lock using the function tipc_port_lock and then releases the lock sometimes using tipc_port_unlock and sometimes using spin_unlock_bh(p_ptr->publ.lock). tipc_port_unlock simply does the spin_unlock_bh, but it seems cleaner to use it everywhere. The problem was fixed using the following semantic patch. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ struct port *p_ptr; @@ p_ptr = tipc_port_lock(...) ... ( p_ptr = tipc_port_lock(...); | ?- spin_unlock_bh(p_ptr->publ.lock); + tipc_port_unlock(p_ptr); ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: Jon Paul Maloy <maloy@donjonn.com> Signed-off-by: David S.
