iommu/omap: Mark pm functions __maybe_unused (96088a20) · Commits · 戴 / test

The runtime_pm functions are unused when CONFIG_PM is disabled: drivers/iommu/omap-iommu.c:1022:12: error: unused function 'omap_iommu_runtime_suspend' [-Werror,-Wunused-function] static int omap_iommu_runtime_suspend(struct device *dev) drivers/iommu/omap-iommu.c:1064:12: error: unused function 'omap_iommu_runtime_resume' [-Werror,-Wunused-function] static int omap_iommu_runtime_resume(struct device *dev) Mark them as __maybe_unused to let gcc silently drop them instead of warning.
