regulator_disable(9)

💅 regulator_disable(9) — Kernel API Manual ✨

okay so bestie, we're in the kernel API manual, section 9, and today's main character is regulator_disable(9) 🎀 like yes we're literally turning the power off, slay.

---

✨ NAME ✨

regulator_disable — disable regulator output 💅

---

🌸 SYNOPSIS 🌸

int regulator_disable (struct regulator *regulator );

lowkey the whole flex is just one function call, iykyk 🦋

---

🎀 ARGUMENTS 🎀

• regulator — the regulator source, aka the thing you're about to switch off, no cap ✨

---

💖 DESCRIPTION 💖

Disable the regulator output voltage or current. 🔌✨ That's it, that's the vibe — you are turning the thing off.

but bestie hear me on this one: calls to regulator_enable must be balanced with calls to regulator_disable. ⚖️ like for real for real, it's a matched set. You can't just be out here disabling more times than you enabled, that is NOT the vibe. fr fr. 👑

---

⚠️ NOTE ⚠️

okay this is the part where you actually pay attention 🫶:

this will only disable the regulator output if no other consumer devices have it enabled, the regulator device supports disabling and machine constraints permit this operation.

so basically 🥺 it's not just your call — three things gotta line up: nobody else is still using it, the hardware can even do disabling, and the machine constraints say yes. main character energy but with a committee approval, honestly. 😭

---

⭐ RETURN ⭐

0 on success or a negative error number on failure. so if you get 0, you ate 💅 and if you get negative, that's the error number telling you what went wrong. slay responsibly. 🔥
