Subject: [PATCH v3 3/9] coresight: platform: Fix refcounting for graph nodes
Date: Fri, 27 Jul 2018 11:15:31 +0100 [thread overview]
Message-ID: <1532686537-12380-4-git-send-email-suzuki.poulose@arm.com> (raw)
In-Reply-To: <1532686537-12380-1-git-send-email-suzuki.poulose@arm.com>
The coresight driver doesn't drop the references on the
remote endpoint/port nodes. Add the missing of_node_put()
calls.
Reported-by: Mathieu Poirier <mathieu.poirier@linaro.org>
Signed-off-by: Suzuki K Poulose <suzuki.poulose@arm.com>
