[PATCH v2 0/3] ASoC: soc-pcm: cleanup code
Hi Mark
These are v2 of soc-pcm cleanup code. v1 had 6 patches, but I separated into 2 parts. This is 1st part of it.

This patch moves dpcm_set_fe_update_state() to top side. This is prepare for cleanup soc-pcm.c

soc-pcm has dpcm_set_fe_update_state() to update FE's runtime_update (except dpcm_fe_dai_do_trigger() which needs to update it without it). OTOH, it doesn't have BE's update function.
O: dpcm_set_fe_update_state() X: dpcm_set_be_update_state()
This patch add BE's dpcm_set_fe_update_state()

Getting rate/channels/sample_bits from param needs fixed method. This patch adds new soc_pcm_set_dai_params() and replace existing code.

Hi Mark
These are v2 of soc-pcm cleanup code. v1 had 6 patches, but I separated into 2 parts. This is 1st part of it.
I actually already queued patches 1-4 of v1 - it's testing ATM. Are there any changes here or is it just splitting things up?
1-3 are same, and I updated 4-6. But OK. I will check latest branch
Thank you for your help !!
