The SNVS power key driver has suspend/resume functions that are accessed using SIMPLE_DEV_PM_OPS, which hide the reference when CONFIG_PM_SLEEP is not set, resulting in a warning about unused functions: drivers/input/keyboard/snvs_pwrkey.c:183:12: error: 'imx_snvs_pwrkey_suspend' defined but not used [-Werror=unused-function] drivers/input/keyboard/snvs_pwrkey.c:194:12: error: 'imx_snvs_pwrkey_resume' defined but not used [-Werror=unused-function] This adds __maybe_unused annotations to let the compiler know it can silently drop the function definition.
