From 1d37ae50671435e842c58b1429dfb0a6d065c42a Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Thu, 25 Aug 2016 15:19:07 -0600 Subject: coresight: tmc: Delete an unnecessary check before the function call "kfree" The kfree() 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.
