From c3491eca37fe1e333c7daf48f00df1efadc71b0b Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Thu, 28 Jul 2016 15:48:59 -0700 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.
