Subject: [PATCH 1/5] iommu/vt-d: Remove unused dma map/unmap trace events
Date: Tue, 23 Mar 2021 09:05:56 +0800	[thread overview]
Message-ID: <20210323010600.678627-2-baolu.lu@linux.intel.com> (raw)
In-Reply-To: <20210323010600.678627-1-baolu.lu@linux.intel.com>

With commit c588072bba6b5 ("iommu/vt-d: Convert intel iommu driver to
the iommu ops"), the trace events for dma map/unmap have no users any
more. Cleanup them to make the code neat.
