From 7af348be47fd2df5d276add2167b5838d48ba044 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Wed, 4 Feb 2015 15:56:58 +0100 Subject: [PATCH] net: ep93xx_eth: Delete unnecessary checks before the function call "kfree" The kfree() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: H Hartley Sweeten Signed-off-by: David S.
