Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: audio-graph-card: fix refcount leak of cpu_ep in __graph_for_each_link() The of_get_next_child() returns a node with refcount incremented, and decrements the refcount of prev. So in the error path of the while loop, of_node_put() needs be called for cpu_ep.
