tee_device_register(9)

💅 tee_device_register(9) — like, the TEE device registration glow-up

okay so bestie, welcome to the Kernel API Manual page for tee_device_register(9) — yes that (9) means it's a kernel-internals section page, iykyk 🎀. Sit down, grab a strawberry drink 🍓, and let's get into it.

---

✨ NAME ✨

tee_device_register — literally just "Registers a TEE device". that's it. that's the whole vibe 😌

---

🌸 SYNOPSIS 🌸

int tee_device_register (struct tee_device *teedev );

one function, one pointer, one int coming back at you. simple. iconic. no cap. 💅

---

🦋 ARGUMENTS 🦋

• teedev — the device you're registering. like, the actual thing. hand it over 🫶

---

👑 DESCRIPTION 👑

so here's the tea, and it's lowkey important 🔥: if this function fails, you still need to call tee_device_unregister to remove the teedev. yes, even on the fail path. it's giving "clean up after yourself, bestie" energy. don't leave your teedev just lying around in the group chat 💀

---

⭐ RETURN ⭐

< 0 on failure. that's the whole return contract, and we respect it 🌈

fr fr, negative means something went wrong — and remember the DESCRIPTION: unmask that cleanup energy with tee_device_unregister anyway. 🧚
