💖 ieee802154_free_hw(9) 💖

okay so welcome to the Kernel API Manual, bestie — we're talking about ieee802154_free_hw today and honestly it's giving cleanup era ✨

---

🌸 NAME 🌸

ieee802154_free_hw — frees the hardware descriptor, no cap 🫶

---

🎀 SYNOPSIS 🎀

void ieee802154_free_hw (struct ieee802154_hw *hw );

---

🦋 ARGUMENTS 🦋

• hw — the hardware you're freeing. that's it, that's the whole parameter 💅

---

✨ DESCRIPTION ✨

so here's the vibe: this function frees everything that was allocated — and when we say everything, we mean everything, including the private data for the driver. it's the full send cleanup, the icon of letting go 🌈

⚠️ but bestie listen to me: you must call ieee802154_unregister_hw before calling this function. not after, not "eh probably fine", not "I'll do it later". before. this is the one rule and the way that it is non-negotiable 😭💀
