💅 devm_regulat...ter_notifier(9) — the Kernel API Manual one 🎀

okay so bestie, you found the page for devm_regulator_register_notifier from the Kernel API Manual. it's a devres-flavoured lil wrapper and honestly it's giving "i set it up and the kernel cleans it up for me" main character energy ✨

---

🌸 NAME 🌸

devm_regulator_register_notifier — Resource managed regulator_register_notifier

like, the notifier registration, but with a babysitter. 👑

---

✨ SYNOPSIS ✨

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

that's the whole signature, copy it exactly, do not @ me 🙈

---

🫶 ARGUMENTS 🫶

• regulator — regulator source 💖 (this is the regulator you're listening to)
• nb — notifier block 🦋 (the thing that gets notified)

---

🔥 DESCRIPTION 🔥

okay so here's the tea: the notifier will be registers under the consumer device, and it will automatically be unregistered when the source device is unbound. 🎀

like literally, you don't have to do the cleanup yourself — devres handles it. no cap. that's the whole vibe. the wording in the original is literally "will be registers" and "automatically be unregistered", so bestie i'm telling you exactly what it says, grammar quirks and all 💅

and that's the page, bestie!! 🧚 from ./drivers/regulator, dated October 2026, and the manual section is still devm_regulat...ter_notifier(9) because some titles are just too long for their own good 😭 mwah 💜
