From mboxrd@z Thu Jan 1 00:00:00 1970 From: Baoquan He Subject: [Patch v2] x86, ACPI: Fix the wrong assignment when Handle apic/x2apic entries Date: Fri, 12 Aug 2016 15:21:47 +0800 Message-ID: <1470986507-24191-1-git-send-email-bhe@redhat.com> Return-path: Received: from mx1.redhat.com ([209.132.183.28]:42638 "EHLO mx1.redhat.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751148AbcHLHcI (ORCPT ); Fri, 12 Aug 2016 03:32:08 -0400 Sender: linux-acpi-owner@vger.kernel.org List-Id: linux-acpi@vger.kernel.org To: mingo@kernel.org Cc: rjw@rjwysocki.net, linux-acpi@vger.kernel.org, linux-kernel@vger.kernel.org, x86@kernel.org, Baoquan He By pure accident the bug makes no functional difference, because the only expression where we are using these values is (!count && !x2count), in which the variables are interchangeable, but it makes sense to fix the bug nevertheless.
