Can't we make this a stub when !PM_SLEEP?

#ifdef CONFIG_PM_SLEEP
static int intel_pinctrl_pm_init(struct intel_pinctrl *pctrl)
{
...

#else
static inline int intel_pinctrl_pm_init(struct intel_pinctrl *pctrl)
{
	return 0;
}
#endif

Then this still looks like a function call and not like some weird
conditional.
