Subject: [PATCH 57/97] tpm_emulator: Translate TPM error codes to strings
Date: Tue, 1 Oct 2019 18:45:36 -0500 [thread overview]
Message-ID: <20191001234616.7825-58-mdroth@linux.vnet.ibm.com> (raw)
In-Reply-To: <20191001234616.7825-1-mdroth@linux.vnet.ibm.com>
From: Stefan Berger <stefanb@linux.vnet.ibm.com>
Implement a function to translate TPM error codes to strings so that
at least the most common error codes can be translated to human
readable strings.
Signed-off-by: Stefan Berger <stefanb@linux.ibm.com>
Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com>
(cherry picked from commit 7e095e84ba0b7c0a1ac45bc6824dace2fd352e56)
