Subject: [PATCH 4.9 15/34] of: unittest: fix memory leak in unittest_data_add
Date: Fri,  8 Nov 2019 19:50:22 +0100
Message-ID: <20191108174635.453042112@linuxfoundation.org> (raw)
In-Reply-To: <20191108174618.266472504@linuxfoundation.org>

From: Navid Emamdoost <navid.emamdoost@gmail.com>

[ Upstream commit e13de8fe0d6a51341671bbe384826d527afe8d44 ]

In unittest_data_add, a copy buffer is created via kmemdup. This buffer
is leaked if of_fdt_unflatten_tree fails. The release for the
unittest_data buffer is added.

Fixes: b951f9dc7f25 ("Enabling OF selftest to run without machine's devicetree")
