✨ ish_device_disable(9) ✨

okay so bestie, welcome to the ish_device_disable(9) page — it lives in the Kernel API Manual and honestly? it's a short one, but it serves. let's get into it 💅

---

🌸 NAME 🌸

ish_device_disable — Disable ISH device

that's it. that's the whole name. short, sweet, iconic.

---

⭐ SYNOPSIS ⭐

void    ish_device_disable (struct ishtp_device *dev );

look at that signature. void return, so it gives you nothing back — no cap, it's giving mysterious main character energy. and it takes exactly one thing. one. 🎀

---

🦋 ARGUMENTS 🦋

• dev — ISHTP device pointer. yeah. that's your one (1) input. a pointer to the ISHTP device. handle it with care bestie 🫶

---

💖 DESCRIPTION 💖

so here's the tea: ish_device_disable disables the ISH by clearing host ready to inform the firmware.

literally that's the whole vibe. you clear host ready, and the firmware finds out. like sending a text that just says "we're done here" 💀

no hidden extras, no secret flags, no side quests. it does the one thing and it does it slayfully. ✨
