From 8f9d41b430ae03ec63d544c34c31a82507b9e473 Mon Sep 17 00:00:00 2001 From: Yijing Wang Date: Tue, 20 May 2014 20:37:50 +0800 Subject: [PATCH] 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.
