+Subject: [PATCH] backends/libinput: Fix crash upon receiving motion absolute
+ events
+
+The input events can be processed when the workspace is not available,
+e.g. during startup or shutdown, so add a corresponding guard.
+
+As a long term plan, we need to decouple Workspace from low-level input
+backend parts, but it will be a too invasive change for now.
