You would have to add __maybe_unused here for this to work as intended.

Again, this requires __maybe_unused.

And again: __maybe_unused
I would suggest to test compile the code with CONFIG_PM_SLEEP disabled.

Hi Coiby
As already pointed by Fabrice Gasnier for similar patch "[PATCH 10/15] iio: adc: stm32: remove unnecessary CONFIG_PM_SLEEP"
When compiling with W=1 and CONFIG_PM_SLEEP disabled, we got the following warnings:
drivers/watchdog/st_lpc_wdt.c:265:12: warning: ‘st_wdog_resume’ defined but not used [-Wunused-function]
265 | static int st_wdog_resume(struct device *dev)
| ^~~~~~~~~~~~~~
drivers/watchdog/st_lpc_wdt.c:251:12: warning: ‘st_wdog_suspend’ defined but not used [-Wunused-function]
251 | static int st_wdog_suspend(struct device *dev)
| ^~~~~~~~~~~~~~~
Can you add missing "__maybe unused" attribute ?
Thanks
Patrice
