When CONFIG_PM_SLEEP is disabled, we get a harmless warning
drm/hisilicon/hibmc/hibmc_drm_drv.c:115:12: error: ‘hibmc_pm_resume’ defined but not used [-Werror=unused-function] drm/hisilicon/hibmc/hibmc_drm_drv.c:97:12: error: ‘hibmc_pm_suspend’ defined but not used [-Werror=unused-function]
Marking the functions as __maybe_unused avoids the warning without having to add an #ifdef.
