From: Stefan Berger <stefanb@xxxxxxxxxxxxx>
Address the following issue detected by the kernel test robot when
there's no certificate file at the time when checking for the type
of key in the cert:
Can't open certs/signing_key.pem for reading, No such file or directory
The simplest solution is to redirect openssl's stderr output to /dev/null.
Fixes: 28d62d945ded ("certs: Trigger creation of RSA module signing key if it's not an RSA key")
