fwnode_find_reference(9)

🦋 fwnode_find_reference(9) 🦋

okay so bestie, this is the Kernel API Manual entry for fwnode_find_reference(9) — and yes, it's literally the “find a named reference to a fwnode_handle” girlie. 💅✨

---

🌸 NAME 🌸

fwnode_find_reference — find named reference to a fwnode_handle 💖

✨ SYNOPSIS ✨

struct fwnode_handle * fwnode_find_reference (const struct fwnode_handle
       *fwnode , const char *name , unsigned int index );

🎀 ARGUMENTS 🎀

• fwnode — the firmware node where you're looking for the reference, bestie. 👀
• name — the name of the reference. like, the label you're hunting for. 🏷️
• index — the index of the reference. 🔢

💖 DESCRIPTION 💖

index can be used when the named reference holds a table of references. no cap, that's the whole vibe. 📚

⚠️ okay important: the caller is responsible for calling fwnode_handle_put on the returned fwnode pointer. do not forget, bestie — this one is on you. 🫶

🌈 RETURN 🌈

a pointer to the reference fwnode, when found. otherwise, it returns an error pointer. 💀✨
