snd_hda_code...p_for_unbind(9)

💅 snd_hda_codec_cleanup_for_unbind — a whole moment

okay so first things first, bestie: this page lives in the Kernel API Manual, and the function's full glow-up name is snd_hda_codec_cleanup_for_unbind. Yes the header truncates it to snd_hda_code...p_for_unbind(9) — that's just the man page being dramatic and mysterious, don't let it gaslight you 🎀

✨ NAME ✨

snd_hda_codec_cleanup_for_unbind — Prepare codec for removal

like, it's the "pack your bags, we're leaving" function for a codec device. no cap 🧳

---

🌸 SYNOPSIS 🌸

void snd_hda_codec_cleanup_for_unbind (struct hda_codec *codec );

she takes exactly one (1) argument and returns void, so don't go looking for a return value, she simply does not have one 💅

🦋 ARGUMENTS 🦋

• codec — codec device to cleanup. that's it. that's the whole argument. she's the codec you're tidying up before she gets yeeted out of the system 🫶

🌈 the sign-off 🌈

and that's the page, bestie!! this little beauty hangs out under ./sound/hda/common, and the doc itself is dated October 2026, filed under snd_hda_code...p_for_unbind(9) in the Kernel API Manual. go forth and clean up those codecs responsibly. mwah 💋✨🍓
