Right.  My mistake.
I compile tested only and didn't notice the badly formed string.

Mind if I move the time to the front like this?

+#define dbg(format, arg...)                                            \
+do {									\
+	if (i8042_debug)						\
+		printk(KERN_DEBUG KBUILD_MODNAME ": [%d]" format),	\
+                      (int)(jiffies - i8042_start_time), ##arg);	\
+} while (0)

I'll resubmit a pr_<level> series for drivers/input/serio
today/tomorrow with this change.
