Subject: shell: don't crash if a pointer's focus is null
X-Git-Tag: upstream/0.1.8~706
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3d0fc76dd5069b813ab636d6ca199ea0e494748f;p=profile%2Fivi%2Fweston-ivi-shell.git

shell: don't crash if a pointer's focus is null

It's possible for a pointer's focus to be null, e.g. because
the focus surface has been bestroyed. Prevent a crash when
that happens and a client takes too long to respond to a ping.
