Subject: [PATCH v4 14/15] iommu/vt-d: Remove duplicated code for device hotplug
Date: Sat, 25 May 2019 13:41:35 +0800 [thread overview]
Message-ID: <20190525054136.27810-15-baolu.lu@linux.intel.com> (raw)
In-Reply-To: <20190525054136.27810-1-baolu.lu@linux.intel.com>
The iommu generic code has handled the device hotplug cases.
Remove the duplicated code.
