Message-Id: <1537471099-19781-5-git-send-email-mathieu.poirier@linaro.org> Date: Thu, 20 Sep 2018 13:17:39 -0600 From: Mathieu Poirier <mathieu.poirier@...aro.org> To: gregkh@...uxfoundation.org Cc: linux-kernel@...r.kernel.org Subject: [PATCH 04/44] coresight: platform: Fix leaking device reference From: Suzuki K Poulose <suzuki.poulose@....com> We don't drop the reference on the remote device while parsing the connection, held by bus_find_device(). Fix this by duplicating the device name and dropping the reference.
