From: Conor McLoughlin conor.mcloughlin@intel.com
commit 333e18c5cc74438f8940c7f3a8b3573748a371f9 upstream.
The RSA private key for the first form should have version, prime1, prime2, exponent1, exponent2, coefficient values 0. With non-zero values for prime1,2, exponent 1,2 and coefficient the Intel QAT driver will assume that values are provided for the private key second form. This will result in signature verification failures for modules where QAT device is present and the modules are signed with rsa,sha256.
