Add PLAT_S3C24XX, ARCH_S3C64XX and ARCH_S5PV210 dependencies to SAMSUNG_PM_DEBUG config option to hide it on Exynos platforms. Then convert Exynos code to not require <plat/pm-common.h> header (use pr_debug() directly instead of S3C_PMDBG() macro and remove redundant s3c_pm_*() calls).

My mistake, I will correct it in v3. [ The idea was to make SAMSUNG_PM_DEBUG consistent with other options depending on DEBUG_KERNEL. However after I've checked them it turned out that there is no such consistency. I intended to revert this change but ultimately I forgot about it.. ] Best regards, -- Bartlomiej Zolnierkiewicz Samsung R&D Institute Poland Samsung Electronics ^ permalink raw reply [flat|nested] 3+ messages in thread
