From 27aa9ceebe6a14dcc961126bd2a3f462dfba256b Mon Sep 17 00:00:00 2001 From: Mathieu Poirier Date: Tue, 2 Feb 2016 14:13:57 -0700 Subject: [PATCH] coresight: coresight_unregister() function cleanup In its current form the code never frees csdev->refcnt allocated in coresight_register(). There is also a problem with csdev->conns that is freed before device_unregister() rather than in the device release function. This patch addresses both issues by moving kfree(csdev->conns) to coresight_device_release() and freeing csdev->refcnt, also in the same function.
