Arnd Bergmann	fd99f796a2	iommu/mediatek: Mark PM functions as __maybe_unused ... 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.
