Description

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.
