snd_hdac_str...lease_locked(9)

💖 NAME 💖

snd_hdac_stream_release_locked — okay so this is the one that releases the assigned stream, bestie. That's it, that's the whole vibe.

---

✨ SYNOPSIS ✨

void snd_hdac_stream_release_locked (struct hdac_stream *azx_dev );

---

🎀 ARGUMENTS 🎀

• azx_dev — the HD-audio core stream you're releasing 🦋 (yes, that specific one, don't be weird about it)

---

🌸 DESCRIPTION 🌸

So here's the tea: this function releases the stream that was assigned by snd_hdac_stream_assign. Like, it's the "you're done now, go home" moment for a stream 🫶.

⚠️ Big important note, no cap: the bus->reg_lock needs to be taken at a higher level. So you (or whoever called you) has to already be holding it — this function is literally named _locked, bestie, the clue is right there 💅.
