AFAIR, it worked properly for the suspend part showing more logs. Unless it changed, the feature looks still useful.

Yes, it shows few additional messages from mach/plat specific suspend code but it breaks the assumption that features (even debug ones) work correctly and make you invest time in debugging known broken code. In case it is needed/useful (which should be rather rare situation) one can always easily revert the commit locally.

OK, let's remove it. However in such case this change leaves useless S3C_PMDBG and other s3c_pm_* in Exynos code. They should go away along with SAMSUNG_PM_DEBUG.

"Samsung PM Suspend debug" feature (controlled by SAMSUNG_PM_DEBUG config option) is not working properly (debug messages are not displayed after resume) on Exynos platforms because GPIOs restore code is not implemented. Add PLAT_S3C24XX, ARCH_S3C64XX and ARCH_S5PV210 dependencies to SAMSUNG_PM_DEBUG config option to hide it on Exynos platforms.
