[ Upstream commit c7eb900f5f45eeab1ea1bed997a2a12d8b5907bc ]
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.
