Just note, checkpatch complains following, so fixed to use pr_warn()
when I applied.
WARNING: Prefer pr_warn(... to pr_warning(...

WARNING: struct dev_pm_ops should normally be const
#622: FILE: drivers/pwm/pwm-samsung.c:583:
+static struct dev_pm_ops pwm_samsung_pm_ops = {
fixed to add const when I applied.
