Subject: [PATCH v3 1/2] ASoC: ak4642: Minor cleanups in probe()
Date:   Thu, 31 Aug 2023 21:47:33 +0100
Message-Id: <20230831204734.104954-2-biju.das.jz@bp.renesas.com>
In-Reply-To: <20230831204734.104954-1-biju.das.jz@bp.renesas.com>
References: <20230831204734.104954-1-biju.das.jz@bp.renesas.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Some minor cleanups:
 Replace local variable np with dev_fwnode()
 Replace dev_err()->dev_err_probe().
 Remove comma in the terminator entry for OF table.
 Drop a space in the terminator entry for ID table.
