From fe0bf1185ddf7e9d193cfe397ed1414d91526e19 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Tue, 18 Nov 2014 13:23:43 +0100 Subject: NFS: Deletion of unnecessary checks before the function call "nfs_put_client" The nfs_put_client() 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.
