From 6d7651015c16e1ee3576edbb5e88ba24f0f1fe7a Mon Sep 17 00:00:00 2001 From: Andrew Murray Date: Thu, 29 Aug 2019 14:28:34 -0600 Subject: coresight: etm4x: Remove superfluous setting of os_unlock In addition to unlocking the OS lock, etm4_os_unlock will also set the os_unlock flag. Therefore let's avoid unnecessarily setting os_unlock flag outside of this function.
