palmas_pwron_suspend(9)

💤 palmas_pwron_suspend

okay bestie, so this is a page from the Kernel API Manual — yes, the kernel has lore and yes it's documented 😌 — and today's main character is palmas_pwron_suspend, the suspend handler. It's giving "time for bed, power button" energy.

---

✨ SYNOPSIS ✨

int palmas_pwron_suspend (struct device *dev );

it takes one thing and returns an int. simple. iconic. no notes 💅

---

🫶 ARGUMENTS 🫶

• dev — the power button device. that's it, that's the whole argument list, she's low maintenance 💖

---

🎀 DESCRIPTION 🎀

so when the system goes to sleep, this handler does two (2) jobs fr fr:

• cancels all pending work items for the power button — sorry girlies, the queue is closed 🚫
• sets up the irq for wakeup — so the power button can still wake everybody back up ⏰✨

basically: clean up the vibes, but leave the door unlocked so the button can knock when it's time to rise and shine 🌸

---

👑 RETURN 👑

returns 0. that's it. zero. a whole clean slate, no drama, no cap 🙈
