Subject: [PATCH 03/25] iommu/vt-d: Remove unnecessary exported symbol
Date: Tue, 12 Jul 2022 08:08:46 +0800 [thread overview]
Message-ID: <20220712000908.3431936-4-baolu.lu@linux.intel.com> (raw)
In-Reply-To: <20220712000908.3431936-1-baolu.lu@linux.intel.com>
The exported symbol intel_iommu_gfx_mapped is not used anywhere in the
tree. Remove it to avoid dead code.
