tee_device_get(9)

💖 NAME 💖

okay so this is the tee_device_get(9) page from the Kernel API Manual, and it's literally about one tiny but important job: Increment the user count for a tee_device. bestie, it's giving "small function, big responsibility" energy 💅

---

✨ SYNOPSIS ✨

bool tee_device_get (struct tee_device *teedev );

---

🎀 ARGUMENTS 🎀

• teedev — Pointer to the tee_device. that's the whole argument, no cap 🫶

---

🦋 DESCRIPTION 🦋

here's the tea: if tee_device_unregister has been called and the final user of teedev has already released the device, this function will fail to prevent new users from accessing the device during the unregistration process. 😭

like, it's doing its little gatekeeping thing, but in that specific situation it cannot keep the new users out while unregistration is happening. noted, bestie 📝

---

🌸 RETURN 🌸

returns true if teedev remains valid, otherwise false. that's the vibe check: valid = true, not valid = false ✨
