🌸 NAME 🌸

power_supply_unregister — Remove this power supply from system 🫶 like, bye babe, you're out of the system now ✨

---

⭐ SYNOPSIS ⭐

void power_supply_unregister (struct power_supply *psy );

that's it, that's the whole vibe check 💖

---

🦋 ARGUMENTS 🦋

• psy — Pointer to power supply to unregister 👑 literally just a pointer to the power supply you're kicking out of the system, no cap

---

🌈 DESCRIPTION 🌈

So the tea 🍓: this function removes this power supply from the system. That's the whole main character moment ✨

And about the memory situation — the resources of the power supply get freed either here or on the last power_supply_put call. so it's giving "cleanup happens now, or whenever the last put happens" 💀 no leak drama, it's handled, iykyk 🧚

lowkey important detail bestie: it's not always freed right here — sometimes it waits for that last power_supply_put call. don't forget that part!! 🙈
