omap_hwmod_for_each(9)

💖 NAME 💖

okay so bestie, welcome to the omap_hwmod_for_each(9) page from the Kernel API Manual 💅 this one is literally “call function for each registered omap_hwmod” — a little for-each gremlin for hwmods, and it’s giving “loop over every registered one.”

---

✨ SYNOPSIS ✨

int omap_hwmod_for_each (int (*fn)(struct omap_hwmod *oh, void *data) ,
void *data );

copy that signature exactly, bestie — yes, the comma and everything 🫶

---

🎀 ARGUMENTS 🎀

• fn — pointer to a callback function. this is the function that gets called for each one.
• data — void * data to pass to callback function. yep, it gets handed straight to the callback.

---

🦋 DESCRIPTION 🦋

Call fn for each registered omap_hwmod, passing data to each function. fn must return 0 for success or any other value for failure. If fn returns non-zero, the iteration across omap_hwmods will stop and the non-zero return value will be passed to the caller of omap_hwmod_for_each. fn is called with omap_hwmod_for_each held.

so like, if your callback is not returning 0, the whole little parade stops and that non-zero value gets yeeted back to whoever called omap_hwmod_for_each 😭 and yes: fn is called with omap_hwmod_for_each held — that part is not a vibe, it’s a fact.

bestie warning: fn returning non-zero isn’t just a little hiccup — it stops the whole iteration and sends that value back to the caller. no cap 🔥
