💅 cdx_device_add(9) — like, the CDX device one

okay bestie, welcome to the Kernel API Manual ✨ this one's called cdx_device_add(9) and it's genuinely so straightforward you're gonna slay it on the first read, i promise 🫶

🌸 NAME 🌸

cdx_device_add — Add a CDX device 💖

So like, this function adds a CDX device on the CDX bus, literally exactly as per the device parameters the caller hands over. And that's not even all — it also creates and registers an associated Linux generic device for you. two-for-one, iconic 👑

---

✨ SYNOPSIS ✨

int cdx_device_add (struct cdx_dev_params *dev_params );

that's it. that's the whole vibe check 🔥

---

🎀 ARGUMENTS 🎀

• dev_params — the device parameters associated with the device to be created. like, everything the new device needs to know about itself, passed in by you 💅

---

⭐ RETURN ⭐

• -errno on failure 😭
• 0 on success 🎉

no cap, that's the whole scale. zero is the good one. negative errno means something went sideways, and it tells you which something via the errno value, periodt.
