🌸 pm8001_chip_iounmap(9) 🌸

okay bestie so this is a page straight out of the Kernel API Manual and it's literally about pm8001_chip_iounmap — the little cleanup gremlin of the pm8001 world 💅

---

✨ NAME ✨

pm8001_chip_iounmap — the one that unmaps the stuff that got mapped when everything was initialized. like, it undoes the mapping situation. which mapped when initialized. yeah. that. 🎀

---

✨ SYNOPSIS ✨

void pm8001_chip_iounmap (struct pm8001_hba_info *pm8001_ha );

it returns void, so don't go looking for a return value, she gives you nothing back and that's iconic of her honestly 🦋

---

✨ ARGUMENTS ✨

• pm8001_ha — our hba card information 💖 like, the whole vibe of the card, passed straight in. this is our hba card info, bestie, we're emotionally attached.
