drm_connector_unregister(9)

💅 drm_connector_unregister — the "okay bye bestie" for connectors ✨

So this is a page straight out of the Kernel API Manual (yes, the kernel has its own manual, slay), and it's about ✨ unregistering ✨ a connector. Buckle up, it's short but it matters 🎀

---

🌸 NAME 🌸

drm_connector_unregister — unregister a connector. That's it, that's the whole vibe. 💅

---

✨ SYNOPSIS ✨

void drm_connector_unregister (struct drm_connector *connector );

Basically: you hand it a connector, it does The Thing, and it returns nothing (void — no receipts, no notes, just vibes). 🫶

---

🦋 ARGUMENTS 🦋

• connector — the connector you're unregistering, i.e. the main character of this whole operation 👑

---

💖 DESCRIPTION 💖

Okay so the tea: this function unregisters the userspace interfaces for a connector. Like, it packs up the connector's little public-facing socials and takes them offline. 📵

But here's the part everyone gets wrong, so listen up bestie: drivers should only call this for dynamic connectors (MST), and only ones that were explicitly registered by calling drm_connector_dynamic_register. Those are the only ones who need you to manually log them out.

Every other connector — the static ones — gets unregistered automatically by DRM core. So drivers shouldn't be calling this function for those at all, mmkay? The core handles it. No cap. 🧚

---

🙈 NOTE 🙈

Existing uses of this function in drivers for static connectors should be a nop already — and they're scheduled to be removed. So if you're out here calling it on static connectors, it's basically a no-op era that's getting sunsetted. Lowkey time to clean that up. 💀

And that's the whole page, bestie 🫶 — brought to you by the fine folks over at ./drivers/gpu/drm, stamped October 2026. Go forth and only unregister your dynamic connectors, mwah 💋✨
