pm_relax(9) — Kernel API Manual, but make it cute 🫶

✨ NAME ✨

pm_relax — tells the PM core that processing of a wakeup event has ended. That’s the whole main character description, no cap. 💖

💅 SYNOPSIS 💅

okay so the signature is literally this:

void pm_relax (struct device *dev );

---

🫶 ARGUMENTS 🫶

• dev — the device that signaled the event. That’s it, bestie; this function keeps it simple.

---

🌸 DESCRIPTION 🌸

When you call pm_relax, it executes __pm_relax for the dev’s wakeup source object. That’s the move, fr fr. ✨
