• substream — Pointer to the PCM substream structure 👀
• params — Pointer to the hardware params structure 🌸
• stream_config — Stream configuration for the SoundWire audio stream 🎧
• port_config — Port configuration for the SoundWire audio stream 🔌

🌸 DESCRIPTION 🌸

okay so this function gives you a basic conversion from the hw_params structure over to SoundWire configuration structures — iconic, honestly ✨

but bestie, at a minimum you will also need to set the port number in the port config. you may also override more of the setup, or, if you're a complex user, not use this helper at all and open-code everything. no cap 💅
