Subject: [RESEND PATCH] ARM: Fix refcount leak in axxia_boot_secondary
Date: Wed,  1 Jun 2022 13:05:48 +0400	[thread overview]
Message-ID: <20220601090548.47616-1-linmq006@gmail.com> (raw)

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")
