Subject: [PATCH] ASoC: atmel: Add missing of_node_put() in at91sam9g20ek_audio_probe
Date:   Mon,  7 Mar 2022 12:45:39 +0000
Message-Id: <20220307124539.1743-1-linmq006@gmail.com>
Precedence: bulk

This node pointer is returned by of_parse_phandle() with refcount
incremented in this function.
Calling of_node_put() to avoid the refcount leak.

Fixes: 531f67e41dcd ("ASoC: at91sam9g20ek-wm8731: convert to dt support")
