Hello,

this looks fine, but the commit prefix should either be
"ASoC: rockchip: i2s_tdm:" or "ASoC: rockchip: i2s-tdm" to align
with previous commits. We've already broken convention once before,
hence the two names, and I'd rather not have this convention broken
again.

Kind regards,
Nicolas Frattaroli
