4.17-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nicholas Mc Guire <hofrat@xxxxxxxxx>
[ 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.
Fixes: 8961def56845 ("PCI: xilinx: Add Xilinx AXI PCIe Host Bridge IP driver")
