int powercap_unregister_zone (struct powercap_control_type *control_type

it's giving "returns an int, takes two pointers, minds its own business." slay. 🫶

---

✨ ARGUMENTS ✨

• control_type — a pointer to the valid instance of a control_type. yes, it has to be valid, bestie, we're not out here passing vibes and NULLs. 💀
• power_zone — a pointer to the valid zone instance for a control_type. one zone, one control_type, matching energy. 🦋

✨ DESCRIPTION ✨

so what does it actually do? it's used to unregister a zone device for a control_type. that's the whole job. a zone that was registered gets unregistered. closure, growth, moving on. 🌸

⚠️ but listen — the caller should make sure that children for this zone are unregistered first. that's the one rule. do the kids' goodbyes before the parent's goodbye, or you're gonna have a bad time. not me warning you twice, i'm warning you once but with feeling. 😭
