Subject: [PATCH] powerpc/spufs: Fix refcount leak in spufs_init_isolated_loader
Date: Fri,  3 Jun 2022 16:15:42 +0400	[thread overview]
Message-ID: <20220603121543.22884-1-linmq006@gmail.com> (raw)

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")
