Subject: [PATCH v2 1/7] iommu/vt-d: Don't return error when device gets right domain
Date: Wed, 12 Jun 2019 08:28:45 +0800	[thread overview]
Message-ID: <20190612002851.17103-2-baolu.lu@linux.intel.com> (raw)
In-Reply-To: <20190612002851.17103-1-baolu.lu@linux.intel.com>

If a device gets a right domain in add_device ops, it shouldn't
return error.

Fixes: 942067f1b6b97 ("iommu/vt-d: Identify default domains replaced with private")
