From: Arnd Bergmann <arnd@xxxxxxxx> Without CONFIG_IOMMU_API, the nvdec_writel() function is unused, causing a warning: drivers/gpu/drm/tegra/nvdec.c:48:13: error: 'nvdec_writel' defined but not used [-Werror=unused-function] 48 | static void nvdec_writel(struct nvdec *nvdec, u32 value, unsigned int offset) | ^~~~~~~~~~~~ As this is a trivial wrapper around an inline function, mark it as inline itself, which avoids the warning as well.
