media_device_usb_allocate(9)

💅 media_device_usb_allocate(9)

okay so bestie, welcome to the Kernel API Manual — this is the page for media_device_usb_allocate, and honestly? it's giving "small function, big responsibilities" energy. ✨

---

🌸 NAME 🌸

media_device_usb_allocate — allocate and return struct &media device 🎀

---

✨ SYNOPSIS ✨

struct media_device * media_device_usb_allocate (struct usb_device *udev
, const char *module_name , struct module *owner );

like, that's the whole signature, no cap. 🫶

---

🦋 ARGUMENTS 🦋

• udev — a struct usb_device pointer, bestie. that's the USB device you're handing over. 🔌
• module_name — should be filled with KBUILD_MODNAME. yes, literally that macro. don't get creative. 💅
• owner — a struct module pointer; for a driver you want THIS_MODULE here. and real talk: THIS_MODULE is null for a built-in driver, but it's safe even when THIS_MODULE is null. so no panic, okay? 🧚

👑 DESCRIPTION 👑

so here's the vibe check 👇

this interface should be called to allocate a Media Device when multiple drivers share the usb_device and the media device. like, sharing is caring but someone's gotta do the allocating. 🙈

what it actually does: it allocates the media_device structure and calls media_device_usb_init to initialize it. that's it, that's the whole moment. ⭐

fr fr, it's the "should be called" — this isn't a maybe, it's the intended path when you've got drivers sharing stuff. 🔥
