Subject: [PATCH] ARM: imx: Fix refcount leak in imx_src_init
Date:   Wed,  9 Mar 2022 10:29:25 +0000
Message-Id: <20220309102929.16306-1-linmq006@gmail.com>
Precedence: bulk

The of_find_compatible_node() function returns a node pointer with
refcount incremented, We should use of_node_put() on it when done
Add the missing of_node_put() to release the refcount.

Fixes: 9fbbe6890c88 ("arm/imx6q: add core drivers clock, gpc, mmdc and src")
