commit 9ed199d7098098d48778b706d057efa9f3497d58
Author: Mrunal Sovani <mruna...@samsung.com>
Date: Thu Sep 24 14:57:10 2015 +0100
Evas smart: Add obj type safety check to callback_del.
Summary:
Evas_Smart_Data retrieved from eo_data_scope_get might be NULL
in case the input Evas_Object is not valid Evas_Object.
The smart data gets dereferenced and can cause a crash if its NULL
Hence return in case smart data is NULL.
@fix
