why the kernel-doc style comment?
Nothing intentional, will fix this!

not sure I get why you added the __ prefix, does it have any semantic meaning?
Nope, just to mark them it as internal function, as the function name is very much similar to q6asm_dai_compr_set_params() callback! I will try to come up with better naming and also move the indirection changes to a separate patch!

all these indirection changes could have gone in a earlier patch, this adds a lot of changes that make this patch long to review. Same comment for all formats

it's rather odd, the initialization above uses next_track_stream_id = 0?
Vaild stream ids start from 1, So we are toggling this between 1 and 2. So when we set next_track_stream_id to 0, that means we have opened the new next stream id and is set to prtd->stream_id. This logic is to ensure that we are not going to open next stream id twice!
