Subject: [PATCH] ARM: milbeaut: Fix refcount leak in m10v_smp_init
Date: Thu, 12 May 2022 12:15:53 +0400	[thread overview]
Message-ID: <20220512081554.28562-1-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: 9fb29c734f9e ("ARM: milbeaut: Add basic support for Milbeaut m10v SoC")
