Subject: [PATCH v2 5/7] ASoC: mediatek: mt8188: combine afe component registration
Date:   Fri, 21 Apr 2023 18:09:03 +0800
Message-ID: <20230421100905.28045-6-trevor.wu@mediatek.com>
In-Reply-To: <20230421100905.28045-1-trevor.wu@mediatek.com>

Precedence: bulk

There is no benefit to separate two components for AFE, so DAI driver
registration is moved to dev_snd_soc_register_component to merge these
two components.
