ASoC: mediatek: add the .probe() callback in mt2701_afe_pcm_dai_component
For the sake of uniformity, this patch adds a callback mt2701_afe_pcm_probe() in mt2701_afe_pcm_dai_component to retrieve the regmap - the canonical way to obtain the pointer.. Doing so, we could switch to use devm_snd_soc_register_component() to register the component driver. Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Mark Brown <broonie@kernel.org>
