when CONFIG_PM is not defined, the compiler warns CC drivers/dma/tegra210-adma.o drivers/dma/tegra210-adma.c:635:12: warning: 'tegra_adma_runtime_suspend' defined but not used [-Wunused-function] static int tegra_adma_runtime_suspend(struct device *dev) ^ drivers/dma/tegra210-adma.c:644:12: warning: 'tegra_adma_runtime_resume' defined but not used [-Wunused-function] static int tegra_adma_runtime_resume(struct device *dev) ^ Although driver uses SET_RUNTIME_PM_OPS but doesn't add protection for these symbols causing warning when CONFIG_PM is not defined, so add CONFIG_PM around these symbols.
