tee_device_set_dev_groups(9)

✨ tee_device_set_dev_groups(9) ✨

okay so bestie, welcome to the Kernel API Manual, section 9, and today's main character is tee_device_set_dev_groups — she's a tiny little setter function and honestly? she ate. 🎀

---

🌸 NAME 🌸

tee_device_set_dev_groups — Set device attribute groups

like, that's it, that's her whole job, and she does it flawlessly 💅

---

🦋 SYNOPSIS 🦋

void tee_device_set_dev_groups (struct tee_device *teedev , const struct
       attribute_group **dev_groups );

no return value, no drama, just vibes ✨

---

🍓 ARGUMENTS 🍓

• teedev — Device to register. this is the tee device you're handing stuff to, she's the whole point 🫶
• dev_groups — Attribute groups. the groups in question. the attribute-y ones. you're giving them to teedev 😌

---

🔥 DESCRIPTION 🔥

so what she does is: Assigns the provided dev_groups to the teedev so that it can be registered later with tee_device_register. it's giving "prep now, slay later" 👑

Calling this function is optional — not mandatory, no pressure, you do you. BUT. and this is the important part, bestie —

If you do call it, it must be called before tee_device_register. no cap. order matters. do not come for her after registration, she will not be able to help you 😭
