Subject: [PATCH] fgraph: Remove unused value

The variable `ret` is assigned a value which is unused.
Fix this by removing the redundant `ret = 0;` assignment.

This issue was reported by Coverity Scan.
Report:
CID 1600916: (#1 of 1): Unused value (UNUSED_VALUE)
assigned_value: Assigning value 0 to ret here,
but that stored value is overwritten before it can be used.
