[ Upstream commit 8d1667200850f8753c0265fa4bd25c9a6e5f94ce ]
The apq8016 driver leaves the of-node refcount at aborting from the loop of for_each_child_of_node() in the error path. Not only the iterator node of for_each_child_of_node(), the children nodes referred from it for codec and cpu have to be properly unreferenced.
