tipc: remove direct accesses to own_addr field in struct tipc_net
As a preparation to changing the addressing structure of TIPC we replace all direct accesses to the tipc_net::own_addr field with the function dedicated for this, tipc_own_addr(). There are no changes to program logics in this commit. Acked-by: Ying Xue <ying.xue@windriver.com> Signed-off-by: Jon Maloy <jon.maloy@ericsson.com> Signed-off-by: David S.
