Subject: staging: wlan-ng: remove unused variable
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c732041b72506f4f6622debe057bd8f35ce2009f;p=linux-beck.git

staging: wlan-ng: remove unused variable

This patch removes variables that were 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;
