[PATCH 4.19 171/287] powerpc/spufs: Fix refcount leak in spufs_init_isolated_loader

[Greg Kroah-Hartman]

From: Miaoqian Lin <linmq006@xxxxxxxxx>

[ Upstream commit 6ac059dacffa8ab2f7798f20e4bd3333890c541c ]

of_find_node_by_path() returns remote device nodepointer with
refcount incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.

Fixes: 0afacde3df4c ("[POWERPC] spufs: allow isolated mode apps by starting the SPE loader")
