snd_dmaengin...m_unregister(9)

✨ snd_dmaengine_pcm_unregister — the Kernel API Manual page, bestie edition ✨

okay so real talk, this is a section 9 kernel API page, and the whole name got squished by the terminal into snd_dmaengin...m_unregister(9) — iconic of the pager, honestly, but the actual function is snd_dmaengine_pcm_unregister. it's a section 9 joint, iykyk 💅

🌸 NAME 🌸

snd_dmaengine_pcm_unregister — Removes a dmaengine based PCM device

like, it's the goodbye function. the cleanup era. the "we're literally done here" moment 🫶

---

🦋 SYNOPSIS 🦋

void snd_dmaengine_pcm_unregister (struct device *dev );

no return value bestie, it's void — it does the thing and bounces, no receipts, no notes ✨

---

🎀 ARGUMENTS 🎀

• dev — the parent device that the PCM was registered with. yes, that device. the one you handed over originally. it's giving "return the borrowed hoodie to the exact same person" energy 🙈

---

💖 DESCRIPTION 💖

Removes a dmaengine based PCM device that was previously registered with snd_dmaengine_pcm_register.

that's the whole vibe. you registered it, now you unregister it. symmetry! balance! main character energy! ⭐

friendly reminder that this page is literally 3 lines of description and then vibes. the .c file is where the actual lore lives, no cap 🧚
