set_rtc_noop(), get_rtc_noop() are after booting, therefore their __init
annotation is wrong.
A crash was observed on an x86 platform where CMOS RTC is unused and
disabled via device tree. set_rtc_noop() was invoked from ntp:
sync_hw_clock(), although CONFIG_RTC_SYSTOHC=n, however sync_cmos_clock()
doesn't honour that.
Workqueue: events_power_efficient sync_hw_clock
RIP: 0010:set_rtc_noop
Call Trace:
update_persistent_clock64
sync_hw_clock
Fix this by dropping the __init annotation from set/get_rtc_noop().
