[ Upstream commit 2aacace6dbbb6b6ce4e177e6c7ea901f389c0472 ] In attach_node_and_children memory is allocated for full_name via kasprintf. If the condition of the 1st if is not met the function returns early without freeing the memory. Add a kfree() to fix that. This has been detected with kmemleak: Link: https://bugzilla.kernel.org/show_bug.cgi?id=205327 It looks like the leak was introduced by this commit: Fixes: 5babefb7f7ab ("of: unittest: allow base devicetree to have symbol metadata") Signed-off-by: Erhard Furtner <erhard_f@mailbox.org> Reviewed-by: Michael Ellerman <mpe@ellerman.id.au> Reviewed-by: Tyrel Datwyler <tyreld@linux.ibm.com> Signed-off-by: Rob Herring <robh@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
