From 7b1115bbb700c7e46923bbbf007c04f04230873c Mon Sep 17 00:00:00 2001 From: Julian Wiedmann Date: Tue, 15 Aug 2017 17:02:40 +0200 Subject: [PATCH] s390/qeth: remove extra L2 adapterparms query qeth_l2_request_initial_mac() queries the device for its supported adapterparms, even though they already have been queried as part of the device's high-level setup. Remove that extra call. The only call chain for qeth_l2_request_initial_mac() is __qeth_l2_set_online() qeth_core_hardsetup_card() qeth_query_setadapterparms() qeth_l2_setup_netdev() qeth_l2_request_initial_mac() qeth_query_setadapterparms() , and we only reach qeth_l2_request_initial_mac() if the first adapterparms query succeeds. Hence removing the second query results in no loss of functionality. Signed-off-by: Julian Wiedmann Acked-by: Ursula Braun Signed-off-by: David S.
