Subject: [PATCH] drm/gma500: fix memory leaks
Date:   Sun, 18 Aug 2019 22:12:57 -0500
Message-Id: <1566184395-7615-1-git-send-email-wenwen@cs.uga.edu>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

In mdfld_dsi_output_init(), if mdfld_dsi_pkg_sender_init() fails, the
execution is directed to the 'dsi_init_err0' label. However, some
previously allocated buffers and resources are not deallocated, leading to
memory/resource leaks. To fix this issue, revise the 'dsi_init_err0' label.
