[PATCH v3 0/2] iommu: Fix spelling mistakes

[Zhen Lei]

v2 --> v3:
1) Add some new fixes for the latest linux-next:
   drivers/iommu/fsl_pamu_domain.c:366: Traverese ==> Traverse
   drivers/iommu/mtk_iommu.c:977: Uppon ==> Upon
   drivers/iommu/intel/svm.c:488: shuld ==> should
   drivers/iommu/intel/svm.c:920: requeset ==> request
   drivers/iommu/intel/dmar.c:2131: Specifiction ==> Specification
2) Add a new fix "Additionally, The ==> Additionally, the", discovered by Will Deacon
3) Add some new fixes for the header files of iommu/iova
   The header files to be checked are as follows:
   include/linux/iommu*.h
   include/linux/iova.h
   include/uapi/linux/iommu.h
4) Changes to files "iova.h" and "iova.c" are grouped into a new patch.


v1 --> v2:
1. Merge into one patch
2. Add a new fix "appropriatley --> appropriately" in iommu.c, discovered by John Garry
