device_wakeup_detach(9)

🌙 device_wakeup_detach(9) — the kernel API manual, bestie edition 🎀

okay so real talk, this page lives in the Kernel API Manual family (that's the manual name, yes, and yes it's giving "official documentation but make it make sense" 💅), and it's literally about severing the link between a device and its wakeup source object. nothing dramatic, just a clean breakup ✨

---

✨ NAME ✨

device_wakeup_detach — detach a device's wakeup source object from it, periodt 💔

---

🌸 SYNOPSIS 🌸

struct wakeup_source * device_wakeup_detach (struct device *dev );

---

🦋 DESCRIPTION 🦋

so like. after it returns, dev will not be treated as a wakeup device any more. that's the whole vibe check. one moment it's a wakeup device, next moment it's just... a device. no cap 🫶

---

💖 ARGUMENTS 💖

• dev — the device you're detaching the wakeup source object from. that's the one. she's the main character of this call 🎀
