[alsa-devel] [PATCH v2 1/3] ASoC: mediatek: mt8183: fix tdm out data align issue

[Jiaxin Yu]

Mt8183 tdm out support S16_LE/S24_LE/S32_LE formats. When output S32_LE,
we need set hd_align so that memif can output MSB 24bits. When output
S24_LE, we need reset hd_align so that memif can output LSB 24bits.
