From: Arnd Bergmann <arnd@xxxxxxxx> Depending on the configuration, there are no references to these two helpers: drivers/phy/tegra/xusb.c:1286:12: error: 'tegra_xusb_padctl_resume_noirq' defined but not used [-Werror=unused-function] 1286 | static int tegra_xusb_padctl_resume_noirq(struct device *dev) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/phy/tegra/xusb.c:1276:12: error: 'tegra_xusb_padctl_suspend_noirq' defined but not used [-Werror=unused-function] Mark them as __maybe_unused to shut up the warnings without adding fragile #ifdefs.
