fwnode_get_n...e_child_node(9)

💖 NAME 💖

Okay so this is the fwnode_get_n...e_child_node(9) page from the Kernel API Manual — aka the full-on fwnode_get_next_available_child_node bestie. Its whole job: return the next available child node handle for a node ✨

🌸 SYNOPSIS 🌸

struct fwnode_handle * fwnode_get_next_available_child_node (const
       struct fwnode_handle *fwnode , struct fwnode_handle *child );

🎀 ARGUMENTS 🎀

• fwnode — Firmware node to find the next child node for. Like, the parent node you're poking around in 💅
• child — Handle to one of the node's child nodes or a NULL handle.

🦋 DESCRIPTION 🦋

The caller is responsible for calling fwnode_handle_put on the returned fwnode pointer. And note — this function also puts a reference to child unconditionally. No cap, that part is important 🫶
