4.20-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 9eb40fa2cd2d1f6829e7b49bb22692f754b9cfe0 ]
of_find_node_by_path() acquires a reference to the node returned by it
and that reference needs to be dropped by its caller. soc_is_tegra()
doesn't do that, so fix it.
