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.
