Subject: [PATCH] dmaengine: tegra210-adma: Fix unused function warnings
Date: Tue, 9 Jul 2019 16:32:58 +0800 [thread overview]
Message-ID: <20190709083258.57112-1-yuehaibing@huawei.com> (raw)
If CONFIG_PM is not set, build warnings:
drivers/dma/tegra210-adma.c:747:12: warning: tegra_adma_runtime_resume defined but not used [-Wunused-function]
static int tegra_adma_runtime_resume(struct device *dev)
drivers/dma/tegra210-adma.c:715:12: warning: tegra_adma_runtime_suspend defined but not used [-Wunused-function]
static int tegra_adma_runtime_suspend(struct device *dev)
Mark the two function as __maybe_unused.
