iort_find_domain_token(9)

bestie, welcome to the iort_find_domain_token(9) page from the Kernel API Manual — it’s a tiny little lookup era, and we’re gonna get through it together 💖✨

🌸 NAME 🌸

iort_find_domain_token — find the domain token based on the given ITS ID. That’s the whole vibe: you hand it an ITS ID, it goes looking 🕵️‍♀️💅

✨ SYNOPSIS ✨

struct fwnode_handle * iort_find_domain_token (int trans_id );

🎀 ARGUMENTS 🎀

• trans_id — the ITS ID. That’s the thing you’re using for the lookup, periodt 💅

🦋 RETURN 🦋

When it finds the domain token on the list, it returns that domain token. Otherwise? NULL. That’s it, that’s the whole return journey 😭🫶
