Wen Yang	e12bfa013c	PCI: uniphier: Fix a leaked reference by adding missing of_node_put() ... The call to of_get_child_by_name() returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage. irq_domain_add_linear() also calls of_node_get() to increase refcount, so irq_domain will not be affected when it is released. Detected by coccinelle with the following warnings: ./drivers/pci/controller/dwc/pcie-uniphier.c:283:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 274, but without a corresponding object release within this function. ./drivers/pci/controller/dwc/pcie-uniphier.c:290:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 274, but without a corresponding object release within this function. ./drivers/pci/controller/dwc/pcie-uniphier.c:296:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 274, but without a corresponding object release within this function.
