In the Linux kernel, the following vulnerability has been resolved:

ath10k: Fix error handling in ath10k_setup_msa_resources

The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.

This function only calls of_node_put() in the regular path.
And it will cause refcount leak in error path.
