Hi Arnd,

The rework of the suspend/resume handling uses the wrong #ifdef check, leading
to a build warning without CONFIG_PM_SLEEP:
drivers/pinctrl/samsung/pinctrl-samsung.c:1142:12: error: 'samsung_pinctrl_resume' defined but not used [-Werror=unused-function]
drivers/pinctrl/samsung/pinctrl-samsung.c:1092:12: error: 'samsung_pinctrl_suspend' defined but not used [-Werror=unused-function]
Using a __maybe_unused annotation instead of the #ifdef is a simple way to
avoid this problem class.
Fixes: 2b24efa8e5c5 ("pinctrl: samsung: Replace syscore ops with standard platform device pm_ops")

Thanks for the fix!
