From f3165dc02212e8eaf5cb675f105aac89c6de431c Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Thu, 17 Feb 2022 12:09:28 -0800 Subject: [PATCH] KVM: selftests: Drop @test param from kvm_create_device() Remove the two calls that pass @test=true to kvm_create_device() and drop the @test param entirely. The two removed calls don't check the return value of kvm_create_device(), so other than verifying KVM doesn't explode, which is extremely unlikely given that the non-test variant was _just_ called, they are pointless and provide no validation coverage.
