Miaohe Lin 566b1bb7d3 KVM: arm/arm64: vgic: Fix potential double free dist->spis in __kvm_vgic_destroy() ... [ Upstream commit 0bda9498dd ] In kvm_vgic_dist_init() called from kvm_vgic_map_resources(), if dist->vgic_model is invalid, dist->spis will be freed without set dist->spis = NULL. And in vgicv2 resources clean up path, __kvm_vgic_destroy() will be called to free allocated resources. And dist->spis will be freed again in clean up chain because we forget to set dist->spis = NULL in kvm_vgic_dist_init() failed path. So double free would happen.
