bonding: check return value of register_netdevice() in bond_newlink()
Very similar to commit 544f287b8495 ("bonding: check error value of register_netdevice() immediately"), we should immediately check the return value of register_netdevice() before doing anything else. Fixes: 005db31d5f5f ("bonding: set carrier off for devices created through netlink") Reported-and-tested-by: syzbot+bbc3a11c4da63c1b74d6@syzkaller.appspotmail.com Cc: Beniamino Galvani <bgalvani@redhat.com> Cc: Taehee Yoo <ap420073@gmail.com> Cc: Jay Vosburgh <j.vosburgh@gmail.com> Signed-off-by: Cong Wang <xiyou.wangcong@gmail.com> Signed-off-by: David S.
