💅 mei_cl_disconnect(9) 💅

okay so welcome to the kernel API manual, bestie — this is section 9 of the manual, and today's main character is mei_cl_disconnect. she's a tiny function with a big job and i'm obsessed with her fr fr ✨

---

🌸 NAME 🌸

mei_cl_disconnect — disconnect host client from the me one 🫶

---

⭐ SYNOPSIS ⭐

int mei_cl_disconnect (struct mei_cl *cl );

like, that's it. that's the whole signature. no cap. 🔥

---

🎀 ARGUMENTS 🎀

• cl — host client 🦋

(yes that's literally the whole description. she's lowkey mysterious. we respect it.)

---

💜 DESCRIPTION 💜

Locking: called under "dev->device_lock" lock 🔒

ok so this is the important part, bestie — she expects you to already be holding that lock when you call her. it's giving "you must be this tall to ride" energy. mind the locking situation, i'm begging 🙈

---

🌈 RETURN 🌈

• 0 on success 💖
• <0 on failure 😭
