Miller" , linux-crypto@vger.kernel.org, Herbert Xu , linux-arm-kernel@lists.infradead.org To: linux-kernel@vger.kernel.org Return-path: Received: from ec2-52-27-115-49.us-west-2.compute.amazonaws.com ([52.27.115.49]:57006 "EHLO osg.samsung.com" rhost-flags-OK-OK-OK-FAIL) by vger.kernel.org with ESMTP id S932966AbdABPiQ (ORCPT ); Mon, 2 Jan 2017 10:38:16 -0500 Sender: linux-crypto-owner@vger.kernel.org List-ID: If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module if the device isn't registered via OF. Export the module alias information using the MODULE_DEVICE_TABLE() macro.
