Message-ID: <1400589472-8544-5-git-send-email-wangyijing@huawei.com> Date: Tue, 20 May 2014 20:37:50 +0800 From: Yijing Wang <wangyijing@...wei.com> To: Joerg Roedel <joro@...tes.org>, David Woodhouse <dwmw2@...radead.org> CC: <iommu@...ts.linux-foundation.org>, <linux-kernel@...r.kernel.org>, Yijing Wang <wangyijing@...wei.com> Subject: [PATCH 4/6] iommu/vt-d: clear the redundant assignment for domain->nid Alloc_domain() will initialize domain->nid to -1. So the initialization for domain->nid in md_domain_init() is redundant, clear it.
