media_device_register(9)

💅 media_device_register — like, the Kernel API Manual edition, bestie ✨

okay so real talk, we're in the <pink>Kernel API Manual</pink> today and the vibe is media_device_register(9) — yes that (9) is doing main character work, don't question it 🎀

---

🌸 NAME 🌸

media_device_register — Registers a media device element 🦋

---

✨ SYNOPSIS ✨

media_device_register (mdev );

that's it. that's the whole thing. short and iconic 💅

---

🎀 ARGUMENTS 🎀

• mdev — pointer to struct media_device. literally just a pointer to the struct, no cap 🫶

---

💖 DESCRIPTION 💖

okay so listen — this is a macro, not a regular function, and what it does is it calls <cyan>__media_device_register</cyan> and passes THIS_MODULE in as the second argument of __media_device_register, which is the owner argument. that's the whole bit. the macro is out here doing the THIS_MODULE homework for you so you don't have to 😭✨

fr fr, the only thing happening here is that THIS_MODULE gets slotted into the owner spot. the way that's literally the entire description 🎀
