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.

Jarkko,

can you please squash this patch into the one it fixes. Unfortunately when rebasing you will have to fix the subsequent patch from this merge error

ifeq ($(openssl_available),yes)
<<<<<<< HEAD
X509TEXT=$(shell openssl x509 -in $(CONFIG_MODULE_SIG_KEY) -text 2>/dev/null)
=======
X509TEXT=$(shell openssl x509 -in $(CONFIG_MODULE_SIG_KEY) -text)
endif
>>>>>>> 87e968848116 (certs: Add support for using elliptic curve keys for signing modules)

to this:


ifeq ($(openssl_available),yes)
X509TEXT=$(shell openssl x509 -in $(CONFIG_MODULE_SIG_KEY) -text 2>/dev/null)
endif

Thanks.
