regulator_suspend(9)

🌙 regulator_suspend(9) — a Kernel API Manual moment 💅

okay bestie, welcome to the Kernel API Manual, section 9, and today's main character is regulator_suspend. it's short, it's sweet, it's giving "one job and it does it" energy. let's get into it 🎀

---

✨ NAME ✨

regulator_suspend — prepare regulators for system wide suspend 😴

---

✨ SYNOPSIS ✨

int regulator_suspend (struct device *dev );

---

✨ ARGUMENTS ✨

• dev — a struct device pointer, and it gets passed straight on to _regulator_suspend. that's the whole gig 🫶

---

✨ DESCRIPTION ✨

so what does it do? it configures each regulator with its suspend operating parameters for state. literally that's it, that's the function. it's the "everybody get comfy, we're going to sleep" moment for your regulators 🌸

---

✨ RETURN ✨

• 0 on success 🎉
• a negative error number on failure 😭
