IMO, changing rdma_port to dma_port should be in patch 3 (ASoC: qcom: rename rdmactl_audif_start to dmactrl_audif_start). However, as I stated in my comments to your RFC submission, this is a nit.

In patch 1 of this series (ASoC: qcom: use snd_dma_alloc/free* apis), you correctly used the platform device for memory allocation. However, that is then replaced by the soundcard device here ...
