drivers: staging: iio: accel: Removed unnecessary variable
Author: Tina Johnson <tinajohnson.1234@gmail.com>
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;
