✨ NAME ✨

iort_get_iort_node — the function that goes and retrieves the iort_node associated with an fwnode 🦋

like, you hand it a firmware node and it hands you back the IORT node that's linked to it. match made in heaven, no cap.

---

🌈 SYNOPSIS 🌈

struct acpi_iort_node * iort_get_iort_node (struct fwnode_handle *fwnode
);

that return type is struct acpi_iort_node * btw — pointer, pointer energy 👑

---

💖 ARGUMENTS 💖

• fwnode — the fwnode associated with the device that you wanna look up 🫶 literally just pass in the firmware node of the device you're curious about, and the lookup happens from there.

---

⭐ RETURN ⭐

on success you get an iort_node pointer back 💫

on failure? NULL. that's it. no drama, just NULL, so pls remember to check it before you dereference, bestie 😭💀
