net: dsa: felix: don't deinitialize unused ports
[ Upstream commit 42b5adbbac03bdb396192316c015fa3e64ffd5a1 ] ocelot_init_port is called only if dsa_is_unused_port == false, however ocelot_deinit_port is called unconditionally. This causes a warning in the skb_queue_purge inside ocelot_deinit_port saying that the spin lock protecting ocelot_port->tx_skbs was not initialized. Fixes: e5fb512d81d0 ("net: mscc: ocelot: deinitialize only initialized ports") Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Sasha Levin <sashal@kernel.org>
