[PATCH 4.17 152/324] PCI: xilinx-nwl: Add missing of_node_put()

From: Greg Kroah-Hartman
Date: Thu Aug 23 2018 - 04:51:52 EST

4.17-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.
