+Subject: [PATCH] x11: Declare variable for the inner loop
+
+Otherwise the outer loop control variable is messed up, and we end
+up with uninitialized axes if there were any more valuators after
+the XIKeyClass one.
+
+This bug was sneakily introduced by fdb9a8e14, many thanks to
+Carlos Soriano for helping spot the source of this bug.
