Hi Chanwoo Choi,
How about using SIMPLE_DEV_PM_OPS instead of SET_SYSTEM_SLEEP_PM_OPS?
SIMPLE_DEV_PM_OPS is simpler as below.
static SIMPLE_DEV_PM_OPS(exynos4_busfreq_pm, NULL, exynos4_busfreq_resume);
However, if runtime pm functions will be added later,
SIMPLE_DEV_PM_OPS is not necessary.
Best regards,
Jingoo Han
