💅 fwnode_graph...ext_endpoint(9) — Kernel API Manual

okay so bestie, welcome to the glow-up edition of the fwnode_graph...ext_endpoint(9) page from the Kernel API Manual ✨ this one's short but she's important, so pay attention 🎀

🌸 NAME 🌸

fwnode_graph_get_next_endpoint — get the next endpoint firmware node, literally that's her whole job 🦋

✨ SYNOPSIS ✨

struct fwnode_handle * fwnode_graph_get_next_endpoint (const struct
fwnode_handle *fwnode , struct fwnode_handle *prev );

🎀 ARGUMENTS 🎀

  • fwnode — pointer to the parent firmware node 👑 like, the one who's holding all the endpoints, she's the mother of the group chat
  • prev — the previous endpoint node, or NULL if you wanna grab the first one 🌱 starting fresh, no baggage, we love a clean slate

💖 DESCRIPTION 💖

okay so here's the tea ☕ — you, the caller, are responsible for calling fwnode_handle_put on the returned fwnode pointer. no cap, that's on you, don't forget it or you're leaking refs and that's not the vibe 🙈

and also — the way that this function also puts a reference to prev unconditionally?? yeah. it does that. so don't go putting it again yourself, bestie, that's double-dipping and the kernel will Not be happy 😭

⭐ RETURN ⭐

an endpoint firmware node pointer 🫶 — or NULL if there are no more endpoints available. that's it, that's the whole answer. NULL = you've reached the end of the line, no more endpoints, go home 🏠
