+Subject: [PATCH libevdev] Don't bother sanitizing disabled event codes
+
+Filter them immediately instead of passing them on and relying on the actual
+event handling code to filter them.
+
+Reproducer: if EV_ABS is disabled on an Apple MagicMouse we still get events
+passed into sanitize_event(). But the code handling EV_ABS events doesn't
+update the state, so we end up complaining about double tracking IDs, even
+though that is not actually correct.
