4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nicholas Mc Guire <hofrat@xxxxxxxxx>
[ 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")
