------------------------------------------------------
From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Subject: nilfs2: deletion of an unnecessary check before the function call "iput"
The iput() 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.
