rcar_fcp_get(9)

💖 NAME 💖

rcar_fcp_get — bestie, this is the one that goes and finds an FCP instance and grabs a reference to it 👑

It's a kernel API manual thing, so like, kernel-space vibes only, iykyk 🧚

---

✨ SYNOPSIS ✨

struct rcar_fcp_device * rcar_fcp_get (const struct device_node *np );

That's the whole call, no cap. It hands you back a struct rcar_fcp_device * and it takes one arg, a const struct device_node *np. Clean. Minimal. Ate. 💅

---

🎀 ARGUMENTS 🎀

• np — the device node of the FCP instance 🦋 like, the actual node you're looking for, that's the one you pass in.

---

🌸 DESCRIPTION 🌸

okay so here's the tea ☕ — rcar_fcp_get goes through the list of registered FCP instances and searches it for the instance that corresponds to the device node you handed it (np). Very "scroll the group chat till you find the right message" energy, honestly 🫶

Then it gives you back a pointer to that FCP instance. Slay ✨

BUT — and this is the important part, bestie — if the instance can't be found, it does not just give you NULL and vibe. It returns an ERR_PTR 😭 so please, for the love of everything, check it properly before you dereference. Do not be out here raw-dogging a pointer, I'm begging 🙈
