_lookup(9)

💅 _lookup — find an omap_hwmod by name (kernel API manual, section 9, bestie)

okay so this is a page from the Kernel API Manual, section 9 — and it's honestly the shortest little icon in the whole omap_hwmod saga. it does exactly one thing and it does it immaculately. we love a lowkey function with main character energy. ✨

🌸 NAME 🌸

_lookup — find an omap_hwmod by name

like, that's it. that's the whole job. and she ate. 💅

---

🎀 SYNOPSIS 🎀

struct omap_hwmod * _lookup (const char *name );

the whole signature, verbatim, no notes. look at her. gorgeous. 🫶

---

🦋 ARGUMENTS 🦋

• name — you hand her a name, and she goes looking for the omap_hwmod with that name. that's the whole assignment fr fr.

---

✨ DESCRIPTION ✨

so basically: she returns a pointer to an omap_hwmod matching name, or NULL if it's not found. 😭

that's the tea. no side quests, no surprises, no cap — either you get your pointer or you get NULL, and you will be checking that NULL, bestie, i'm just saying. 🙈
