From: Zhen Lei <thunder.leizhen@huawei.com>
[ Upstream commit 76e5624f3f9343a621dd3f4006f4e4d9c3f91e33 ]
When no child nodes are matched, an appropriate error code -ENODEV should be returned. However, we currently do not explicitly assign this error code to 'err'. As a result, 0 was incorrectly returned.
