[PATCH] integrity: remove redundant initialization of variable ret

From: Colin King <hidden>
Date: 2020-07-01 13:46:40

From: Colin Ian King <redacted>

The variable ret is being initialized with a value that is never read
and it is being updated later with a new value.  The initialization is
redundant and can be removed.
