What I meant is that this requires consensus to make a change, and so 
far I haven't seen any burning desire from the contributors to revisit 
the 2-step sequence.

I will however modify the code in this patch to implement a SoundWire 
'linkdev' register/unregister function, it'll be much easier to review 
and maintain, and will follow the same pattern as the mlx5 code (all 
errors and domain-specific initializations handled in the same 
function). Draft code being tested is at
