Miller" 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]:49318 "EHLO s-opensource.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1754719AbcJLSzw (ORCPT ); Wed, 12 Oct 2016 14:55:52 -0400 Sender: netdev-owner@vger.kernel.org List-ID: If the driver is built as a module, module alias information isn't filled so the module won't be autoloaded. Add a SPI device ID table and use the MODULE_DEVICE_TABLE() macro so the information is exported in the module.
