I think you mean dev_pm_ops.

This could be static (e.g. see drivers/input/keyboard/gpio_keys.c).
I get:
drivers/mmc/host/dw_mmc.c:2069: warning: ‘dw_mci_suspend’ defined but
not used
drivers/mmc/host/dw_mmc.c:2095: warning: ‘dw_mci_resume’ defined but not
used
when CONFIG_PM=y and CONFIG_PM_SLEEP=n (CONFIG_SUSPEND=n), because the
#ifdef above needs to change to CONFIG_PM_SLEEP (see
SET_SYSTEM_SLEEP_PM_OPS in include/linux/pm.h).
