Subject: [PATCH 3/7] iommu/vt-d: Remove unnecessary exported symbol
Date: Sat, 14 May 2022 09:43:18 +0800 [thread overview]
Message-ID: <20220514014322.2927339-4-baolu.lu@linux.intel.com> (raw)
In-Reply-To: <20220514014322.2927339-1-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.
