tee_device_unregister(9)

✨ tee_device_unregister(9) ✨

okay bestie, welcome to the Kernel API Manual — this one's a tiny little function but it's giving very important cleanup energy, so let's get into it 💅

---

🌸 NAME 🌸

tee_device_unregister — literally removes a TEE device. that's it, that's the whole vibe 🎀

---

⭐ SYNOPSIS ⭐

void tee_device_unregister (struct tee_device *teedev );

no cap, that's the whole signature. returns nothing (void), takes one pointer. iconic minimalism ✨

---

🦋 ARGUMENTS 🦋

• teedev — the device you wanna unregister. the one that's gotta go 👋

---

💖 DESCRIPTION 💖

okay so here's the tea 🍓: you should call this function to remove the teedev even if tee_device_register hasn't been called yet. yep, you read that right — unregistered-but-not-yet-registered is still a valid thing to clean up, so don't be shy about it.

and if teedev is NULL? it literally does nothing. zero. nada. no crash, no drama, just vibes 😌🫶

fr fr though — this is the "even if you haven't registered it yet" clause, so don't skip cleanup just because registration never happened 💀
