+Subject: timekeeping: Fix missing timekeeping_update in suspend path
+
+From: John Stultz <john.stultz@linaro.org>
+
+commit 330a1617b0a6268d427aa5922c94d082b1d3e96d upstream.
+
+Since 48cdc135d4840 (Implement a shadow timekeeper), we have to
+call timekeeping_update() after any adjustment to the timekeeping
+structure in order to make sure that any adjustments to the structure
+persist.
+
+In the timekeeping suspend path, we udpate the timekeeper
+structure, so we should be sure to update the shadow-timekeeper
+before releasing the timekeeping locks. Currently this isn't done.
+
+In most cases, the next time related code to run would be
+timekeeping_resume, which does update the shadow-timekeeper, but
+in an abundence of caution, this patch adds the call to
+timekeeping_update() in the suspend path.
