Subject: [PATCH 4.14 117/217] PCI: xilinx: Add missing of_node_put()

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Nicholas Mc Guire <hofrat@...dl.org>

[ Upstream commit 8c3f9bd851a4d3acf0a0f222d4e9e41c0cd1ea8e ]

The call to of_get_next_child() returns a node pointer with refcount
incremented thus it must be explicitly decremented here after the last
usage.
