Subject: [PATCH 2/6] coresight: core: Fix use of uninitialized pointer
Date: Mon, 14 Jun 2021 11:58:57 -0600 [thread overview]
Message-ID: <20210614175901.532683-3-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <20210614175901.532683-1-mathieu.poirier@linaro.org>
From: Junhao He <hejunhao2@hisilicon.com>
Currently the pointer "sink" might be checked before initialized. Fix
this by initializing this pointer.
