register_re...t_forwarding(9)

💅 register_regulator_event_forwarding(9) 💅

okay bestie, welcome to the Kernel API Manual — we're doing regulator supply event forwarding today and honestly? it's a vibe. sit down, hydrate, let's go 🫶✨

---

🌸 NAME 🌸

register_regulator_event_forwarding — enable supply event forwarding ✨

---

🦋 SYNOPSIS 🦋

int register_regulator_event_forwarding (struct regulator_dev *rdev );

like yes that's the whole signature, no notes 💅

---

🎀 ARGUMENTS 🎀

• rdev — the regulator device. yeah. that's the one. 👑

---

⭐ DESCRIPTION ⭐

so what this does, bestie: it registers a notifier on the regulator's supply, so that supply events get forwarded to the consumer regulator via the deferred work handler. that's it, that's the whole glow-up ✨ no cap, that's genuinely the entire bit.

---

🔥 RETURN 🔥

• 0 — success, we ate 💅
• -EALREADY — it's already enabled, girl it was already on 🙈
• or a negative error code — something went sideways, not iconic 😭
