of_node_get(9)

💖 of_node_get(9) 💖

okay so real talk, bestie — this is of_node_get(9) from the Kernel API Manual, and it's genuinely one of the sweetest little functions in the whole device-tree cinematic universe. it does exactly one thing and it does it iconically 🎀

---

✨ NAME ✨

of_node_get — Increment refcount of a node

like... that's it. that's the whole gig. and honestly? she ate 💅

---

🌸 SYNOPSIS 🌸

struct device_node * of_node_get (struct device_node *node );

no cap, that signature is the main character. one pointer in, one pointer out 🦋

---

🧚 ARGUMENTS 🧚

• node — the Node to inc refcount. and bestie, NULL is supported — no fr fr, they built that in on purpose <highlight>to simplify writing of callers</highlight>. so you can just vibe and pass NULL through without a whole if statement situation. iykyk 💜

---

⭐ RETURN ⭐

The node with refcount incremented. that's the return value. that's the whole thing. it's giving "you get the node back, but now it's protected" 👑

just remember, bestie — you bumped that refcount, so somebody (you, it's you) has got to put it back down. of_node_put(9) is literally right there in SEE ALSO, she's waiting 🫶
