Miller" Return-path: Received: from mout.kundenserver.de ([217.72.192.74]:53773 "EHLO mout.kundenserver.de" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751337AbdGaVLY (ORCPT ); Mon, 31 Jul 2017 17:11:24 -0400 Sender: linux-crypto-owner@vger.kernel.org List-ID: Without the base RSA code, we run into a link error: ERROR: "rsa_parse_pub_key" [drivers/crypto/ccp/ccp-crypto.ko] undefined! ERROR: "rsa_parse_priv_key" [drivers/crypto/ccp/ccp-crypto.ko] undefined! Like the other drivers implementing RSA in hardware, this can be avoided by always enabling the base support when we build CCP.
