Subject: PCI: faraday: Add missing of_node_put()
Git-commit: 3dc6ddfedc2818eaaa36842fbb049191e0c5e50f
Patch-mainline: v4.18-rc4
References: bsc#1109806
The call to of_get_next_child() returns a node pointer with refcount
incremented thus it must be explicitly decremented here in the error
path and after the last usage.
Fixes: d3c68e0a7e34 ("PCI: faraday: Add Faraday Technology FTPCI100 PCI Host Bridge driver")
