STRUCT FWCTL_DEVICE(9)

💅 NAME 💅

struct fwctl_device — the per-driver registration struct, bestie. Like, this is the little registration baddie each driver gets. ✨

So this page is from the Kernel API Manual, and we are about to get into it. 🎀

---

🌸 SYNOPSIS 🌸

struct fwctl_device {
    struct device dev;
 };

Yes, that's the whole struct. She's simple, she's iconic, she's doing her job. 👑

---

🦋 Members 🦋

• dev — the sysfs device, specifically at class/fwctl/fwctlXX. That's the vibe. 🫶

---

✨ Description ✨

Okay so real talk: every driver instance gets one of these structs, and the driver's private data sits immediately after it. No cap. 💖

This struct is refcounted, and it gets freed by calling fwctl_put. That's literally the cleanup move, so don't forget it. 😭

Lowkey important: refcounted means refcounted. fwctl_put is the one doing the freeing. Periodt. 💅

That's the whole page, bestie. Header energy: struct fwctl_device(9). Footer energy: from ./include/linux, dated October 2026. Slay. 🌈💜
