Descriptions
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: ti: k3-udma-private: Fix refcount leak bug in of_xudma_dev_get()
We should call of_node_put() for the reference returned by
of_parse_phandle() in fail path or when it is not used anymore.
Here we only need to move the of_node_put() before the check.
