regulator_n...r_call_chain(9)

🌸 NAME 🌸

okay so bestie, meet regulator_notifier_call_chain 💅 — her whole job is call regulator event notifier, and she ate, no cap. This is straight out of the Kernel API Manual, page regulator_n...r_call_chain(9), and honestly it's giving quiet-queen-of-the-regulator-subsystem energy 👑.

---

✨ SYNOPSIS ✨

int regulator_notifier_call_chain (struct regulator_dev *rdev , unsigned
long event , void *data );

like, literally that's the signature, copy it exactly, do not come for me about the spacing 🫶.

---

🎀 ARGUMENTS 🎀

• rdev — regulator source. that's the one, that's the regulator we're talking about 🧚
• event — notifier block. yes bestie, the event is the notifier block, that's what the page says, don't @ me 😭
• data — callback-specific data. so it's the data, and it belongs to whatever callback, iykyk 💫

---

💫 RETURN 💫

NOTIFY_DONE.

that's it. that's the return. no drama, no surprises, she simply returns NOTIFY_DONE and moves on 🎀✨

---

🦋 DESCRIPTION 🦋

so the regulator drivers are the ones who call this — that's the whole point, that's the assignment 💅. When a regulator event has occurred, they call regulator_notifier_call_chain to notify the clients about it 🔥. driver calls it, clients get told, everybody knows, periodt 👑

like genuinely that's the entire description, she's a small function with main character energy 🌈.

ngl bestie, this page is short but she's iconic — NOTIFY_DONE and out, that's the vibe check and she passed ✅💅

and that's the whole page, mwah 😘 this gem lives in ./drivers/regulator and the version stamp says October 2026 — see you in the next one, bestie 🦋✨💖
