Subject: [PATCH][next] fs: remove redundant assignment to variable ret

From: Colin Ian King <colin.king@...onical.com>

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

Addresses-Coverity: ("Unused value")
