That only works in combinations with a macro like SET_SYSTEM_SLEEP_PM_OPS(), which makes sure that we do not actually set the .suspend, etc. members of dev_pm_ops when CONFIG_PM_SLEEP is not set, so that the code actually gets compiled out. We cannot use SET_SYSTEM_SLEEP_PM_OPS here, since the suspend and hibernate paths differ.
