The commit dce8d6964ebd ("iommu/amd: Convert to probe/release_device()
call-backs") introduced an unused variable,

drivers/iommu/amd_iommu.c: In function 'amd_iommu_uninit_device':
drivers/iommu/amd_iommu.c:422:20: warning: variable 'iommu' set but not
used [-Wunused-but-set-variable]
  struct amd_iommu *iommu;
