From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnd Bergmann Subject: [PATCH] PCI: tegra: mark PM functions as __maybe_unused Date: Thu, 15 Mar 2018 17:18:39 +0100 Message-ID: <20180315161901.772729-1-arnd@arndb.de> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Thierry Reding , Lorenzo Pieralisi , Bjorn Helgaas , Jonathan Hunter Cc: Arnd Bergmann , Manikanta Maddireddy , Stephen Warren , Vidya Sagar , linux-tegra@vger.kernel.org, linux-pci@vger.kernel.org, linux-kernel@vger.kernel.org List-Id: linux-tegra@vger.kernel.org The new PM support causes a warning when CONFIG_PM is disabled: drivers/pci/host/pci-tegra.c:2482:12: error: 'tegra_pcie_pm_resume' defined but not used [-Werror=unused-function] static int tegra_pcie_pm_resume(struct device *dev) drivers/pci/host/pci-tegra.c:2463:12: error: 'tegra_pcie_pm_suspend' defined but not used [-Werror=unused-function] static int tegra_pcie_pm_suspend(struct device *dev) Marking the functions as __maybe_unused lets the compiler drop them silently instead.
