drivers: staging: iio: meter: Removed unnecessary variable
Variable len is used only to store the return value. Hence len is removed and the return statement modified. Coccinelle was used to detect such removable variables: @rule1@ identifier ret; expression e; @@ -ret = +return e; -return ret; Signed-off-by: Tina Johnson <tinajohnson.1234@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
