🌸 NAME 🌸

r100_hpd_fini — the hpd tear down callback, no cap 💅

---

✨ SYNOPSIS ✨

void r100_hpd_fini (struct radeon_device *rdev );

like, that's the whole signature. that's her. 🫶

---

🦋 ARGUMENTS 🦋

• rdev — a radeon_device pointer 👑 that's the card's whole vibe right there

---

💖 DESCRIPTION 💖

so what she does is tear down the hpd pins used by the card — and just so we're clear, that's the r1xx-r4xx girlies 🌈 and she also disables the hpd interrupts, periodt. 🔥

that's it. that's the function. clean, simple, iconic. ✨

ngl this is the fini one, so think of it as the pack-up-and-go-home moment for the hpd setup, not the party itself 🎀
