em28xx_free_device(9)

💖 em28xx_free_device(9) 💖

okay so bestie, we're in the Kernel API Manual today and honestly? this one is a little snack. it's short, it's sweet, and it's lowkey the cleanup crew for em28xx devices. let's get into it ✨

---

🌸 NAME 🌸

em28xx_free_device — literally just frees an em28xx device, no cap 🫶

---

🎀 SYNOPSIS 🎀

void em28xx_free_device (struct kref *ref );

that's it. that's the whole vibe check. returns void, takes one little pointer, does its thing 💅

---

🦋 ARGUMENTS 🦋

• ref — a struct kref for the em28xx device 🧚 like, this is the refcount handle for the device in question, so it knows which device we're saying bye to.

---

⭐ DESCRIPTION ⭐

so the way this works is: this function gets called when all extensions and the em28xx core unregisters a device. periodt 💀✨ everyone's done with it, the extensions are out, the core is out, and then this runs to free the device.

it's giving end-of-the-group-chat energy but make it kernel 🔥

ngl bestie, this one's a reference-counting situation — ref is a struct kref, so think of it as the device's "who's still here" counter, and this is the part that does the freeing once everyone's gone 🙈

👑 SEE ALSO 👑

• Kernel file ./drivers/media/usb/em28xx/em28xx-cards.c — go read it, iykyk 🍓

and that's the whole page, bestie!! short and iconic, just how we like it 🌈💜

this cutie came to you straight from ./drivers/media/usb/em28xx in October 2026 — mwah, slay, see you in the next manpage 💅💖
