[PATCH 4.9 064/130] PCI: xilinx-nwl: Add missing of_node_put()

[Greg Kroah-Hartman]

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

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

From: Nicholas Mc Guire <hof...@osadl.org>

[ Upstream commit 342639d996f18bc0a4db2f42a84230c0a966dc94 ]

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.

Fixes: ab597d35ef11 ("PCI: xilinx-nwl: Add support for Xilinx NWL PCIe Host 
Controller")
