SET_SYSTEM_SLEEP_PM_OPS has already took good care of CONFIG_PM_CONFIG.

Hi Coiby,

This generates warnings when building with W=1 and CONFIG_PM_SLEEP=n.
Could you please add also "__maybe_unused" attribute in suspend / resume
routines below.

             ^
e.g. like: static int __maybe_unused stm32_adc_...

Same could be done also for runtime PM routines. For my own curiosity,
do you plan to do this as well ?

Best regards,
