From 1e2a8868e0541b7d8870781b714d74ac7cad9a6a Mon Sep 17 00:00:00 2001 From: Zhang Shengju Date: Tue, 9 Feb 2016 10:37:46 +0000 Subject: [PATCH] bonding: use return instead of goto Replace 'goto' with 'return' to remove unnecessary check at label: err_undo_flags. The reason is that 'err_undo_flags' do two things for the first slave device: 1.revert bond mac address if it is set by the slave device. 2.revert bond device type if it's not ARPHRD_ETHER. It's not necessary for the following three places, they changed neither bond mac address nor type. It's straightforward to return directly. Signed-off-by: Zhang Shengju Signed-off-by: David S.
