Subject: [PATCH AUTOSEL 4.4 11/13] of: unittest: fix memory leak in unittest_data_add
Date: Wed, 30 Oct 2019 11:57:49 -0400 [thread overview]
Message-ID: <20191030155751.10960-11-sashal@kernel.org> (raw)
In-Reply-To: <20191030155751.10960-1-sashal@kernel.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")
