The call to of_parse_phandle() returns a node pointer with refcount
incremented thus it must be explicitly decremented after the last
usage.
iproc_msi_init() also calls of_node_get() to increase refcount:
proc_msi_init()
-> iproc_msi_alloc_domains()
-> pci_msi_create_irq_domain()
-> msi_create_irq_domain()
-> irq_domain_create_linear()
-> __irq_domain_add()
so irq_domain will not be affected when it is released.
Detected by coccinelle with the following warnings:
./drivers/pci/controller/pcie-iproc.c:1323:3-9: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 1299, but without a corresponding object release within this function.
