rproc_of_parse_firmware(9)

💅 rproc_of_parse_firmware(9) — Kernel API Manual, bestie edition 🎀

okay so picture this: you're deep in the kernel, it's the Kernel API Manual, and there's this one function that just... gets it. It's giving "I read the device tree so you don't have to." ✨ Lowkey iconic. Let's get into it 🫶

---

✨ NAME ✨

rproc_of_parse_firmware — parse and return the firmware-name 🍓

---

🌸 SYNOPSIS 🌸

int rproc_of_parse_firmware (struct device *dev , int index , const char
**fw_name );

---

🦋 ARGUMENTS 🦋

• dev — a pointer on a struct device that represents a rproc. like, the device we're snooping on 🔍
• index — the index to use for the firmware-name retrieval. which one? that one, bestie 💅
• fw_name — pointer to a character string, and this is where the firmware name gets returned on success. on failure it stays unmodified — untouched, unbothered, main character energy 👑

---

💖 DESCRIPTION 💖

So this is an OF helper function (yes, the device-tree girlies) that parses a device's DT node looking for the "firmware-name" property, and on success it hands you back the firmware name pointer in fw_name. That's it. That's the whole vibe. No cap. 🌈

---

🔥 RETURN 🔥

0 on success, or an appropriate failure. (Not me hoping it's 0 every time 😭)
