+Subject: [PATCH] x86/rtc: Remove __init for runtime functions
+References: bsc#1012628
+Patch-mainline: 6.2.12
+Git-commit: 775d3c514c5b2763a50ab7839026d7561795924d
+
+[ Upstream commit 775d3c514c5b2763a50ab7839026d7561795924d ]
+
+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().
+
