For instance, when a user's failure to launch a SEV guest is caused by an incorrect IOCTL, the following message is reported: kvm: sev_kvm_init: failed to initialize ret=3D-25 fw_error=3D0 kvm: failed to initialize kvm: Operation not permitted While the error message's accurate output should be: kvm: sev_kvm_init: failed to initialize ret=3D-25 fw_error=3D0 kvm: failed to initialize kvm: Inappropriate ioctl for device Fix this by returning the return number directly on the failure path.
