Subject: KVM: arm: Use PTR_ERR_OR_ZERO()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4404b336cf32bf709942067fe71d8b5cf70fb2b2;p=linux.git

KVM: arm: Use PTR_ERR_OR_ZERO()

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
