Summary
In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic-v3: Fix error handling in gic_populate_ppi_partitions
of_get_child_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
When kcalloc fails, it missing of_node_put() and results in refcount
leak. Fix this by goto out_put_node label.
