From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sergei Shtylyov Subject: [PATCH 1/3] ssb: PCI revision ID register is 8-bit wide Date: Fri, 1 Jul 2011 22:31:59 +0400 Message-ID: <201107012231.59532.sshtylyov@ru.mvista.com> Mime-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit To: mb@bu3sch.de, netdev@vger.kernel.org Return-path: Received: from mail.dev.rtsoft.ru ([213.79.90.226]:47190 "HELO mail.dev.rtsoft.ru" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with SMTP id S1757570Ab1GASdt (ORCPT ); Fri, 1 Jul 2011 14:33:49 -0400 Content-Disposition: inline Sender: netdev-owner@vger.kernel.org List-ID: The SSB code reads PCI revision ID register as 16-bit entity while the register is actually 8-bit only (the next 8 bits are the programming interface register). Fix the read and make the 'rev' field of 'struct ssb_boardinfo' 8-bit as well, to match the register size.
