  error pointers.

• 0b6c0ad3c   iommu/mediatek: Fix handling of of_count_phandle_with_args result ... Browse Code »

  The function can return negative value so it should be assigned to signed
  variable. The patch changes also type of related i variable to make code
  more compact and coherent.

  The problem has been detected using patch
  scripts/coccinelle/tests/unsigned_lesser_than_zero.cocci.

• fd99f796a   iommu/mediatek: Mark PM functions as __maybe_unused ... Browse Code »

  When CONFIG_PM is unset, we get a harmless warning for this driver:

  drivers/iommu/mtk_iommu.c:665:12: error: 'mtk_iommu_suspend' defined but not used [-Werror=unused-function]
  drivers/iommu/mtk_iommu.c:680:12: error: 'mtk_iommu_resume' defined but not used [-Werror=unused-function]

  Marking the functions as __maybe_unused gits rid of the two functions
  and lets the compiler silently drop the object code, while still
  doing syntax checking on them for build-time verification.
