+Subject: [PATCH 4/4] weston: Fix touch screen crash issue
+
+Touch screen operation causes the weston to crash with segment fault sometimes.
+The crash occurs when the coordinate (x,y) passed to the weston input module
+is outside the view window, hence the weston compositor is not able to pick
+up a display view and there is no code to detect this condition at function
+notify_touch().
+
+Upstream status: pending
