Subject: [PATCH 1/2] Staging: dgap: Remove unused variable
Date: Sun,  8 Mar 2015 00:02:34 +0300
Message-Id: <1425762154-1898-1-git-send-email-hamohammed.sa@gmail.com>
In-Reply-To: <1425668163-27190-1-git-send-email-hamohammed.sa@gmail.com>
References: <1425668163-27190-1-git-send-email-hamohammed.sa@gmail.com>

This patch removes variable that was used to store only the return value of a function call.

The issue was detected and resolved using the following coccinelle script:

@@
expression ret;
identifier f;
@@

-ret =
+return
	f(...);
-return ret;
