🌸 of_get_parent — Kernel API Manual 🌸

okay so welcome to of_get_parent(9), bestie!! this is the Kernel API Manual entry for it and it's literally the "who's your mom" function of the device tree world 💅 we're talking drivers/of territory, iykyk.

✨ NAME ✨

of_get_parent — get a node's parent if any 🫶

like, if this node has a parent? you're getting it. if not? no parent, no vibes, that's just how it is.

🦋 SYNOPSIS 🦋

struct device_node * of_get_parent (const struct device_node *node );

that's it. one function, one argument, returns a struct device_node *. main character energy fr fr ✨

🎀 ARGUMENTS 🎀

  • node — the node you want the parent of 👑 (original wording: "Node to get parent")

💖 RETURN 💖

so you get back a node pointer, and the refcount is incremented — meaning you own a reference now, bestie, and you are responsible for it 😭 call of_node_put on it when you're done. no leaking refs in this house, periodt 💅

ngl this is the part everyone forgets. don't be everyone. of_node_put it. 🫶
