Subject: [PATCH] KVM: remove redundant code in kvm_arch_vm_ioctl
Date: Mon, 21 Oct 2019 10:52:56 +0800 [thread overview]
Message-ID: <1571626376-11357-1-git-send-email-linmiaohe@huawei.com> (raw)
If we reach here with r = 0, we will reassign r = 0
unnecesarry, then do the label set_irqchip_out work.
If we reach here with r != 0, then we will do the label
work directly. So this if statement and r = 0 assignment
is redundant.
