device_wakeup_disable(9)

💤 device_wakeup_disable(9) — the kernel API manual, bestie edition 💤

okay so this is a page from the Kernel API Manual, section 9, and it's about that one function that tells the kernel "girl, this device is NOT a wakeup source anymore, stop treating her like one." we stan a clean exit. ✨

---

🌸 SYNOPSIS 🌸

void device_wakeup_disable (struct device *dev );

that's it. that's the whole signature. no return value, no drama, just vibes and a void. 💅

---

🎀 ARGUMENTS 🎀

• dev — the device we're handling. that's the one we're about to un-wakeup-ify. she's the main character here 🫶

---

✨ DESCRIPTION ✨

so here's the glow-up routine, in order, no skips:

• detach dev's wakeup source object from it (it's not her accessory anymore 💔)
• unregister that wakeup source object
• and then destroy it. gone. deleted. no cap 🔥

literally a three-step "we are never ever getting back together" for a wakeup source. slay. 💀
