From 96088a203a0b6c7564bc14167eec89c5427fd18e Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 6 Sep 2019 17:15:38 +0200 Subject: [PATCH] iommu/omap: Mark pm functions __maybe_unused 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.
