[PATCH] lib: remove redundant assignment to variable ret
Posted by Colin Ian King 4 years, 6 months ago
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.
