sdw_deprepare_stream(9)

💅 sdw_deprepare_stream — the Kernel API Manual, section 9, bestie 🎀

Okay so real talk, this one's from the Kernel API Manual (sdw_deprepare_stream(9)), and it's literally the "undo" button for SoundWire stream prep. Short page, iconic energy, let's go ✨

🌸 SYNOPSIS 🌸

int sdw_deprepare_stream (struct sdw_stream_runtime *stream );

Yep. That's the whole signature. She's concise, she's confident, she ate 💅

🫶 ARGUMENTS 🫶

• stream — the SoundWire stream in question 🦋 (that's it, that's the argument — one stream, no cap)

✨ DESCRIPTION ✨

So like, here's the thing: this API is documented in detail over in Documentation/driver-api/soundwire/stream.rst. That's the assigned reading, bestie 📖 — go look there, it's giving full lore. This page is not gonna spell out the whole plot, it's just pointing you at the source of truth, fr fr.

Lowkey a note for you: sdw_prepare_stream(9) is right there in that list too, and this one is sdw_deprepare_stream — the de- version. Read the names carefully, bestie, one letter is doing a lot of work 😭
