Subject: [PATCH v4 12/17] KVM: selftests: Drop dead return code from evmcs_vmptrld() and load_evmcs()
Date: Thu, 3 Sep 2026 17:24:18 -0700 [thread overview]
Message-ID: <20260904002423.3154436-13-seanjc@google.com> (raw)
In-Reply-To: <20260904002423.3154436-1-seanjc@google.com>
Drop the return codes from evmcs_vmptrld() and load_evmcs() as they are
hardcoded to return '0' and "true" respectively.
No functional change intended.
