🎀 ARGUMENTS 🎀

• void — no arguments. none. zero. nada. it takes nothing and it wants nothing, queen behavior honestly 👑

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — this function can be used by the AMD-TEE driver to query if there is a TEE with which it can communicate.

that's it. that's the whole job. it's giving "am i talking to anyone rn or am i talking to a wall" energy and honestly relatable 😭💅

🔥 RETURN 🔥

• -ENODEV — there is no TEE available. heartbreaking, devastating, nobody speak to me 💀
