Subject: [PATCH] ARM: Fix refcount leak in axxia_boot_secondary
Git-commit: 7c7ff68daa93d8c4cdea482da4f2429c0398fcde
Patch-mainline: v5.19-rc4
References: git-fixes
of_find_compatible_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.
Fixes: 1d22924e1c4e ("ARM: Add platform support for LSI AXM55xx SoC")
