regulator_unlock_two(9)

💅 regulator_unlock_two — like, the Kernel API Manual page, bestie 🎀

okay so this is regulator_unlock_two(9) from the Kernel API Manual and it's genuinely the shortest little icon — it does exactly one thing and does it flawlessly, no notes 💖

---

✨ NAME ✨

regulator_unlock_two — unlock two regulators. that's it. that's the whole job. two of them. unlocked. slay 🦋

---

✨ SYNOPSIS ✨

void regulator_unlock_two (struct regulator_dev *rdev1 , struct
       regulator_dev *rdev2 , struct ww_acquire_ctx *ww_ctx );

look at her. void return, three params, zero drama. main character energy fr fr 👑

---

✨ ARGUMENTS ✨

• rdev1 — the first regulator. the blueprint. the one you met first 💜
• rdev2 — the second regulator. the plus-one. the duo partner 🫶
• ww_ctx — the w/w mutex acquire context. yes bestie, the wound/wait mutex situation — it's the context, it's required, don't come for me 🙈

---

✨ DESCRIPTION ✨

The inverse of regulator_lock_two. that's literally the entire description and honestly? iconic. no cap. it undoes the thing, it's the anti-lock, the reverse uno card, periodt ✨

lowkey important: inverse of regulator_lock_two means you pair these two up — lock with one, unlock with the other. mismatched pairs are giving chaos 💀

anyway that's the page, bestie — ./drivers/regulator source, version date October 2026, regulator_unlock_two(9) out here keeping it 💯 the whole time. go unlock your two regulators, you got this 💅💖✨
