That made b53 modify unrelated registers and is -one of reasons for a broken BCM5301x support. - -This problem exists for years but DSA_MAX_PORTS usage has changed few -times. It seems the most accurate to reference commit dropping -dsa_switch_alloc() in the Fixes tag. - -Fixes: 7e99e3470172 ("net: dsa: remove dsa_switch_alloc helper") -Signed-off-by: Rafał Miłecki <rafal@milecki.pl> -Signed-off-by: David S.
