Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> PCI: microchip: Fix refcount leak in mc_pcie_init_irq_domains()<br /> <br /> of_get_next_child() returns a node pointer with refcount incremented, so we<br /> should use of_node_put() on it when we don&amp;#39;t need it anymore.<br /> <br /> mc_pcie_init_irq_domains() only calls of_node_put() in the normal path,<br /> missing it in some error paths. Add missing of_node_put() to avoid<br /> refcount leak.
