The patch titled
Subject: zsmalloc: Delete an unnecessary check before the function call "iput"
has been removed from the -mm tree. Its filename was
zsmalloc-delete-an-unnecessary-check-before-the-function-call-iput.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Subject: zsmalloc: Delete an unnecessary check before the function call "iput"
iput() 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.
