+Subject: [PATCH] wayland: do not leak shortcut inhibit data
+
+We would free the shortcut inhibit data only when the client destroys
+its request, which is not the case when the clients itself is
+destroyed, leading to a leak of the shortcut inhibit data.
+
+Free the data on resource destruction instead, and simply destroy the
+resource on destroy request.
