thermal_coo...e_unregister(9)

💖 thermal_cooling_device_unregister — the Kernel API Manual, bestie edition 💖

Okay so this page lives in the Kernel API Manual (section 9, the grown-up kernel-functions section, iykyk) and it's all about yeeting a thermal cooling device out of existence. Let's get into it 🫶

---

✨ NAME ✨

thermal_cooling_device_unregister — literally removes a thermal cooling device. That's it. That's the whole job. Iconic, honestly 💅

---

🌸 SYNOPSIS 🌸

void thermal_cooling_device_unregister (struct thermal_cooling_device
*cdev );

Note the void — this one doesn't hand you back a return value to obsess over. It just does the thing. No cap ✨

---

🦋 ARGUMENTS 🦋

• cdev — the thermal cooling device you want to remove. Like, the one you're sending off into the sunset 🌅. Hand it over and it gets unregistered.

---

🎀 SEE ALSO 🎀

The kernel file this lives in is ./drivers/thermal/thermal_core.c — that's the main character's address 📍. And here's the whole friend group, all of them cross-referenced and accounted for:

• bind_previous_governor(9)
• thermal_set_governor(9)
• thermal_bind_cdev_to_trip(9)
• thermal_unbind_cdev_from_trip(9)
• thermal_cooling_device_register(9)
• devm_thermal_cooling_device_register(9)
• thermal_cooling_device_update(9)
• thermal_zone_device_register_with_trips(9)
• thermal_zone_device_unregister(9)
• thermal_zone_get_zone_by_name(9)

Like the register one is right there if you need to put a device back — the unregister is the breakup, the register is the getting-back-together, we've all been there 😭💜

---

heads up bestie: this is a void function, so there's no error code to check afterwards. Just call it and trust the vibe check 💀
