drivers: staging: iio: meter: Removed unnecessary variable
Author: Tina Johnson <tinajohnson.1234@gmail.com>
Variable ret is used only to store the return value. Hence ret 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;
