+Subject: [PATCH] Fix NULL pointer exception in case of no input device
+
+When weston with wayland-ivi-extension run without input device,
+that crash by NULL access at setup_input_focus function.
+In this case, st_focus->seat_ctx is NULL pointer, but it use
+without NULL check in this function.
+
+This patch add NULL check for st_focus->seat_ctx.
