The at91-pio4 pinctrl driver uses SET_SYSTEM_SLEEP_PM_OPS() to conditionally set the correct suspend/resume options, but they become unused when CONFIG_PM is disabled: drivers/pinctrl/pinctrl-at91-pio4.c:827:12: error: 'atmel_pctrl_suspend' defined but not used [-Werror=unused-function] drivers/pinctrl/pinctrl-at91-pio4.c:847:12: error: 'atmel_pctrl_resume' defined but not used [-Werror=unused-function] This adds __maybe_unused annotations so the compiler knows it can silently drop them instead of warning.
