Did you test this...
Dude, we've been testing the heck out of SoundWire. If you want to see the actual initialization it's in the intel_init.c code: https://github.com/thesofproject/linux/blob/9c7487b33072040ab755d32ca173b75151c0160c/drivers/soundwire/intel_init.c#L231 And this was clearly stated in the cover letter: "Reviewers might object that the code is provided without some required initializations for mutexes and shim masks, they will be added as part of the transition to sdw_master_device - still stuck as of 3/11."
