Subject: [PATCH 4.9 12/25] drm/dp/mst: fix a possible memory leak in fetch_monitor_name()
Date: Mon, 23 May 2022 19:03:30 +0200 [thread overview]
Message-ID: <20220523165746.853184064@linuxfoundation.org> (raw)
In-Reply-To: <20220523165743.398280407@linuxfoundation.org>
From: Hangyu Hua <hbh25y@gmail.com>
commit 6e03b13cc7d9427c2c77feed1549191015615202 upstream.
