+Subject: [PATCH] fcmatch: Set FcResultMatch at the end if the return value is
+ valid.
+
+In the previous code, the result of 'result' in the argument for
+FcFontSetSort() and FcFontSetMatch() wasn't predictable and not reliable to
+check if the return value is valid or not. this change is to ensure if it's
+performed successfully.
