staging: iio: light: remove unused variable
Author: Aya Mahfouz <mahfouz.saif.elyazal@gmail.com>
This patch removes a variable that was simply used to
store the return value of a function call before
returning it.
The issue was detected and resolved using the following
coccinelle script:
@@
identifier len,f;
@@
-int len;
... when != len
when strict
-len =
+return
f(...);
-return len;
