+Subject: [PATCH] clockevent: sun4i: Fill the irq field in the clockevent
+ structure
+
+The clock event structure irq field was not filled previously to the
+interrupt we're using.
+
+This was resulting in the timer not being used at all when using a
+configuration with SMP enabled on a system with several CPUs, and with
+the cpumask set to the cpu_possible_mask.
