Subject: [PATCH v1] iommu/vt-d: Move intel_iommu_gfx_mapped to Intel IOMMU header
Date: Fri, 28 Aug 2020 19:12:11 +0300	[thread overview]
Message-ID: <20200828161212.71294-1-andriy.shevchenko@linux.intel.com> (raw)

Static analyzer is not happy about intel_iommu_gfx_mapped declaration:

.../drivers/iommu/intel/iommu.c:364:5: warning: symbol 'intel_iommu_gfx_mapped' was not declared. Should it be static?

Move its declaration to Intel IOMMU header file.
