From: Greg Kroah-Hartman
Date: Mon Sep 17 2018 - 18:50:31 EST


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

From: Nicholas Mc Guire <hofrat@xxxxxxxxx>

[ Upstream commit b1259519e618d479ede8a0db5474b3aff99f5056 ]

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