I will add the commit log to explain why like below, thanks.
The patch (commit id: a0a6e06d545a753740c9d8d5ce2c4fdd3ab1c021) adding
tracepoints for alarmtimers will build failed on S390 platform, due to
S390 defconfig did not define CONFIG_RTC_LIB macro to define the
rtc_ktime_to_tm() function which is used in this patch. Thus we should
add dummy static inline functions in case CONFIG_RTC_LIB is not
defined.
