device_get_named_child_node(9)

💖 NAME 💖

Okay bestie, welcome to the Kernel API Manual entry for device_get_named_child_node(9). It returns the first matching named child node handle. That's the whole assignment, and it ate. 💅

✨ SYNOPSIS ✨

struct fwnode_handle * device_get_named_child_node (const struct device
       *dev , const char *childname );

🎀 ARGUMENTS 🎀

• dev — the Device you're finding the named child node for.
• childname — the String you're matching against the child node name.

🦋 DESCRIPTION 🦋

So here's the one thing you literally cannot skip, bestie: the caller is responsible for calling fwnode_handle_put on the returned fwnode pointer. That's the responsibility, and it's giving main character energy. Don't ghost it, fr fr. 🫶
