Subject: staging: iio: light: remove unused variable
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d8f6fa2b73894f52f5fc415138a00403ada57891;p=linux-beck.git

staging: iio: light: remove unused variable

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;
