Subject: iommu/vt-d: Clear the redundant assignment for domain->nid
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=8f9d41b430ae03ec63d544c34c31a82507b9e473;p=deliverable%2Flinux.git

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.
