Subject: [PATCH 1/3] coresight: core: Fix use of uninitialized pointer
Date: Thu, 13 May 2021 21:27:47 +0800	[thread overview]
Message-ID: <1620912469-52222-2-git-send-email-liuqi115@huawei.com> (raw)
In-Reply-To: <1620912469-52222-1-git-send-email-liuqi115@huawei.com>

From: Junhao He <hejunhao2@hisilicon.com>

Currently the pointer "sink" might be checked before initialized. Fix
this by initializing this pointer.
