🌸 drm_privacy_screen_unregister_notifier(9) — the kernel API glow-up 💅

okay so bestie, welcome to the kernel API manual — yes, the drm_privacy_...ter_notifier(9) page you accidentally opened at 2am. sit down, hydrate, and let's talk about undoing a notifier registration. it's giving "cleanup era" and honestly? iconic. 🎀

---

✨ NAME ✨

drm_privacy_screen_unregister_notifier — literally just unregister a notifier. that's the whole vibe. no cap. 🦋

---

✨ SYNOPSIS ✨

int drm_privacy_screen_unregister_notifier (struct drm_privacy_screen
*priv , struct notifier_block *nb );

two pointers walk into a function and one of them is about to be so unregistered. 😭

---

✨ ARGUMENTS ✨

• priv — the privacy screen you're dealing with. (the manual's own wording for this one says "Privacy screen to register the notifier with" — and yeah, we're *un*registering here, but that is genuinely what the page says, so don't come for me, I'm just the messenger 🫶)
• nb — the notifier-block for the notifier. (again, the official text says "Notifier-block for the notifier to register" — same energy, same wording, I promise I'm not making this up 💀)

---

✨ DESCRIPTION ✨

so here's the tea: you take a notifier that you previously registered (you did that with drm_privacy_screen_register_notifier, bestie, keep up 💖) and you unregister it. that's it. that's the function. the reverse card. the "we're so back" to someone else's "it's over". 🌈

think of it as tidying up your group chat — you added the notifier, now you're removing it, and the kernel is grateful either way.

---

✨ RETURN ✨

• 0 on success — slay, we love a clean exit 👑
• a negative error code on failure — not slay, but at least it's honest 😭

lowkey a reminder that the whole point of this page is the counterpart to drm_privacy_screen_register_notifier(9) — if you skip the register step there's nothing to unregister, and the vibes will be off. 🙈

and that's the page, bestie! this absolute classic lives over in ./drivers/gpu/drm and the manual's date stamp says October 2026 — so mark your calendars, screenshot it, frame it, whatever you need. sending you good error codes and zero negative returns ✨💜🍓
