Subject: [PATCH] KVM: arm: Use PTR_ERR_OR_ZERO()
Date:   Tue, 28 Nov 2017 23:48:17 +0100
Message-Id: <1511909297-8585-1-git-send-email-gomonovych@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Fix ptr_ret.cocci warnings:
virt/kvm/arm/vgic/vgic-its.c:971:1-3: WARNING: PTR_ERR_OR_ZERO can be used

Use PTR_ERR_OR_ZERO rather than if(IS_ERR(...)) + PTR_ERR
