From: Colin Ian King <colin.i.king@xxxxxxxxx> Subject: lib: remove redundant assignment to variable ret Variable ret is being assigned a value that is never read. If the for-loop is entered then ret is immediately re-assigned a new value. If the for-loop is not executed ret is never read. The assignment is redundant and can be removed.
