regulator_u...ter_notifier(9)

💅 regulator_unregister_notifier(9)

okay so bestie, welcome to the Kernel API Manual ✨ — this one's about regulator_unregister_notifier(9), and ngl it's a short one, but it's important, so let's get into it 🫶

---

✨ NAME ✨

regulator_unregister_notifier — unregister regulator event notifier 🌸

Literally what it says on the tin, no cap.

---

🦋 SYNOPSIS 🦋

int regulator_unregister_notifier (struct regulator *regulator,
                                   struct notifier_block *nb);

---

🎀 ARGUMENTS 🎀

• regulator — the regulator source, aka the main character here 👑
• nb — the notifier block 🧚

---

💖 DESCRIPTION 💖

Unregister regulator event notifier block. That's it, that's the whole vibe 💀 — it's the "undo" for a notifier you registered, so your block stops getting pinged. Periodt.

---

🔥 RETURN 🔥

0 on success or a negative error number on failure — so like, slay if it's zero, and if it's negative, something went sideways 😭

mwah 💋 that's the whole page — it lives at ./drivers/regulator, dated October 2026, and the header up top is the same regulator_u...ter_notifier(9) in the Kernel API Manual (yes it's truncated, the truncation ate the middle, iykyk 😭). go be great 🦋⭐
